## How many factors does 20 have?

If a number can be expressed as a product of two whole numbers, then the whole numbers are called factors of that number.

So, the factors of 20 are 1, 2, 4, 5, 10 and 20..

## What is the smallest number with 5 factors?

16 is the smallest number with exactly 5 divisors. 12 is the smallest number with at least 5 proper divisors. 2310 is the smallest number with five distinct prime factors.

## Is 28 a perfect number?

Perfect number, a positive integer that is equal to the sum of its proper divisors. The smallest perfect number is 6, which is the sum of 1, 2, and 3. Other perfect numbers are 28, 496, and 8,128.

## Where is the divisor located?

The divisor is the number appearing to the left, or outside, of the division bracket, while the dividend appears to the right, or underneath, the division bracket.

## What are numbers that have 4 factors?

n has four factors: 1, a, b, and n. For example, 6 (1, 2, 3, 6) and 10 (1, 2, 5, 10).

## What is the factor of 5?

Table of Factors and MultiplesFactorsMultiples1, 55301, 2, 3, 66361, 77421, 2, 4, 884841 more rows

## What is the GCF of 5 and 10?

Greatest common factor (GCF) of 5 and 10 is 5.

## What are the factors of 81?

81 is a composite number and is 9 squared. 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.

## What is the factor of 4 and 5?

We found the factors and prime factorization of 4 and 5. The biggest common factor number is the GCF number. So the greatest common factor 4 and 5 is 1.

## What is a factor of 4?

4 is the first composite number, and it is 2 squared. 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.

## What are factors of 80?

The factors of 80 are 1, 2, 4, 5, 8, 10, 16, 20, 40 and 80.

## What is divisor formula?

A divisor is a number that divides another number either completely or with a remainder. A divisor is represented in a division equation as: Dividend ÷ Divisor = Quotient. … Thus, both 4 and 5 are divisors of 20.

## What are multiples of 5?

The multiples of 5 are: 5,10,15,20,25,30,35,40,45,50,…

## What are the factors in 10?

The factors of 10 are 1, 2, 5, and 10. You can also look at this the other way around: if you can multiply two whole numbers to create a third number, those two numbers are factors of the third. 2 x 5 = 10, so 2 and 5 are factors of 10. 1 x 10 = 10, so 1 and 10 are also factors of 10.

## 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 are the factors of 21?

The factors of 21 are 1, 3, 7 and 21. Factor pairs of the number 21 are the numbers that result in original number on multiplying them together.

## How do you find the factor of 5?

5 Easy as 1-2-35 is a prime number.Prime factorization: 5 is prime.The exponent of prime number 5 is 1. Adding 1 to that exponent we get (1 + 1) = 2. Therefore 5 has exactly 2 factors.Factors of 5: 1, 5.Factor pairs: 5 = 1 x 5.5 has no square factors that allow its square root to be simplified. √5 ≈ 2.236.
