## What are the factors of 81?

81 = 1 x 81, 3 x 27, or 9 x 9.

Factors of 81: 1, 3, 9, 27, 81.

Prime factorization: 81 = 3 x 3 x 3 x 3 which can also be written 3⁴.

Since √81 = 9, a whole number, 81 is a perfect square..

## How many positive factors are there?

To find the number of factors of a given number, express the number as a product of powers of prime numbers. Now, increment the power of each of the prime numbers by 1 and multiply the result. Therefore, there will 10 factors including 1 and 48. Excluding, these two numbers, you will have 10 – 2 = 8 factors.

## What are the common factors of 16?

The factors for 16 are 1, 2, 4, 8, 16. The two numbers (12 and 16) share common factors (1, 2, 4).

## What is the largest factor of 24?

24 Think You Have a Snow Problem? Try This:24 is a composite number.Prime factorization: 24 = 2 x 2 x 2 x 3, which can be written 24 = 2³ x 3.The exponents in the prime factorization are 3 and 1. … Factors of 24: 1, 2, 3, 4, 6, 8, 12, 24.Factor pairs: 24 = 1 x 24, 2 x 12, 3 x 8, or 4 x 6.More items…•

## What is a factor of 4 and 6?

Greatest common factor (GCF) of 4 and 6 is 2. We will now calculate the prime factors of 4 and 6, than find the greatest common factor (greatest common divisor (gcd)) of the numbers by matching the biggest common factor of 4 and 6.

## What are the factors of a negative number?

Negative numbers can be factors of negative numbers only. However, a positive number always have positive factors. For example, 6 have 1,2,3 and 6 as it’s factors whereas -6 have +1,-1,+2,–2,+3,-3 and +6,-6 as it’s factors.

## What is a factor of 24?

## What number has only 4 factors?

Counting FactorsNum factorsDescription (p and q are primes)4The product of two primes pq has the 4 factors 1, p, q and pq, but also primes cubed have the 4 factors 1, p, p2, p3.5The 4th power of a prime has exactly the 5 factors 1, p, p2, p3, p4.2 more rows

## What are the factors of a number?

The factors of a number are the numbers that divide evenly into the number. For example the factors of the number 12 are the numbers 1, 2, 3, 4, 6 and 12.

## What are factors of 20?

The factors of 20 are the numbers, which produce the result as 20 when a pair of factors are multiplied together. These factors are 1,2,4,5,10 and 20. Factor pairs of the number, that results in original number when multiplied together. To find the factors of a number, 20, we will use the factorization method.

## What is the factor of 26?

26 = 1 x 26 or 2 x 13. Factors of 26: 1, 2, 13, 26. Prime factorization: 26 = 2 x 13.

## What are factors of 90?

We know that the factors of the number 90 are 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, 90.

## What is the factor of 3×3 24?

Algebra Examples Factor 3 3 out of 24 24 . Factor 3 3 out of 3×3+3⋅8 3 x 3 + 3 ⋅ 8 . Rewrite 8 as 23 . Since both terms are perfect cubes, factor using the sum of cubes formula, a3+b3=(a+b)(a2−ab+b2) a 3 + b 3 = ( a + b ) ( a 2 – a b + b 2 ) where a=x and b=2 .

## Which is not factor of 24?

Answer : 1,2,3,4,6,8,12,24, Related Links : Is 24 a rational number?

## What is the divisor of 4?

Example: 4 has for divisors 2 and 1. And 2+1=3 inferior to 4, so 4 is a deficient number. Example: The first deficient numbers are: 1, 2, 3, 4, 5, 7, 8, 9, 10, 11, 13, 14, 15, 16, 17, 19, 21, 22, 23, 25, 26, 27, 29, 31, 32, 33, 34, 35, 37, 38, 39, 41, 43, 44, 45, 46, 47, 49, 50…

## What is a factor in math?

A factor is a number that divides into another number exactly and without leaving a remainder. Most numbers have an even number of factors; however, a square number has an odd number of factors. A prime number has only two factors – the number itself and 1.

## What are the factors of 4?

4 = 1 x 4 or 2 x 2. Factors of 4: 1, 2, 4. Prime factorization: 4 = 2 x 2, which can also be written 4 = 2².

## Are Factors positive?

Factors are usually positive or negative whole numbers (no fractions), so ½ × 24 = 12 is not listed.

## Can divisors be negative?

Thus divisors can be negative as well as positive e.g. divisors of 6 are 1, 2, 3, 6, −1, −2, −3, −6 but one would usually mention the positive ones 1, 2, 3, 6. 1 and −1 divide (are divisors of) every integer, every integer is a divisor of itself and every integer is a divisor of 0.
