## What is the factor of 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..

## Is 17 a perfect square?

A number is a perfect square (or a square number) if its square root is an integer; that is to say, it is the product of an integer with itself. Here, the square root of 17 is about 4.123. … Anyway, 17 is a prime number, and a prime number cannot be a perfect square.

## What is the smallest factor of 25?

25 = 1 x 25 or 5 x 5. Factors of 25: 1, 5, 25. Prime factorization: 25 = 5 x 5, which can also be written 25 = 5².

## What is the GCF of 24 and 18?

We found the factors and prime factorization of 18 and 24. The biggest common factor number is the GCF number. So the greatest common factor 18 and 24 is 6.

## What is the GCF of 21 35 and 49?

Greatest common factor (GCF) of 21 and 35 is 7. We will now calculate the prime factors of 21 and 35, than find the greatest common factor (greatest common divisor (gcd)) of the numbers by matching the biggest common factor of 21 and 35.

## What is the greatest common factor of 15 and 18?

The factors of 18 are 18, 9, 6, 3, 2, 1. The common factors of 15 and 18 are 3, 1, intersecting the two sets above. In the intersection factors of 15 ∩ factors of 18 the greatest element is 3. Therefore, the greatest common factor of 15 and 18 is 3.

## What are the factors of 12 and 18?

In terms of numbers, the greatest common factor (gcf) is the largest natural number that exactly divides two or more given natural numbers. Example 1: 6 is the greatest common factor of 12 and 18. Example 2: 2 is a common factor of 12 and 18, but it is NOT the GREATEST common factor.

## How many whole number factors does 18 have?

six different whole number factorsAnswer and Explanation: There are six different whole number factors of 18. The factors are 1, 2, 3, 6, 9, and 18. Whole numbers are numbers beginning with zero that are…

## Is 18 a perfect square?

Is 18 a perfect square number? A number is a perfect square (or a square number) if its square root is an integer; that is to say, it is the product of an integer with itself. Here, the square root of 18 is about 4.243. Thus, the square root of 18 is not an integer, and therefore 18 is not a square number.

## What are the common factors of 18 and 30?

Greatest common factor (GCF) of 18 and 30 is 6. We will now calculate the prime factors of 18 and 30, than find the greatest common factor (greatest common divisor (gcd)) of the numbers by matching the biggest common factor of 18 and 30.

## Whats the HCF of 15 and 20?

5Greatest common factor (GCF) of 15 and 20 is 5. We will now calculate the prime factors of 15 and 20, than find the greatest common factor (greatest common divisor (gcd)) of the numbers by matching the biggest common factor of 15 and 20.

## Is 18 a triangular number?

0, 1, 3, 6, 10, 15, 21, 28, 36, 45, 55, 66, 78, 91, 105, 120, 136, 153, 171, 190, 210, 231, 253, 276, 300, 325, 351, 378, 406, 435, 465, 496, 528, 561, 595, 630, 666…
