## What are the common factors of 15 and 20?

The gcf of 15 and 20 can be obtained like this: The factors of 15 are 15, 5, 3, 1. The factors of 20 are 20, 10, 5, 4, 2, 1. The common factors of 15 and 20 are 5, 1, intersecting the two sets above.

## What is the GCF of 18 and 27?

The factors of 18 are 1, 2, 3, 6, 9, 18. The factors of 27 are 1, 3, 9, 27. The common factors of 18 and 27 are 1, 3 and 9. The greatest common factor of 18 and 27 is 9.

## What is the GCF of 15 and 27?

We found the factors and prime factorization of 15 and 27. The biggest common factor number is the GCF number. So the greatest common factor 15 and 27 is 3.

## 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.

## What is the HCF of 12 and 15?

The factors of 12 are : 1, 2, 3, 4, 6, 12. The factors of 15 are : 1, 3, 5, 15. 1 and 3 are the only common factors (numbers which are factors of both 12 and 15). Therefore, the highest common factor of 12 and 15 is 3.

## What are all the common factors of 9 and 15?

The gcf of 9 and 15 can be obtained like this: The factors of 9 are 9, 3, 1. The factors of 15 are 15, 5, 3, 1. The common factors of 9 and 15 are 3, 1, intersecting the two sets above.

## What is the HCF and LCM of 9 and 15?

Alternatively, the lcm of 9 and 15 can be found using the prime factorization of 9 and 15: The prime factorization of 9 is: 3 x 3. The prime factorization of 15 is: 3 x 5. Eliminate the duplicate factors of the two lists, then multiply them once with the remaining factors of the lists to get lcm(9,9) = 45.

## What is the GCF for 15 and 25?

The Greatest Common Factor of 15and25 is 5. (the number itself and 1 do not count). The factor(s) of 25 is 5 .

## What is the common factor of 5 15 and 25?

Now, as we can see other than 1, 5 is the common factor in the three factorization, hence 5 is the common factor. Now, HCF is defined as the highest common factor. and here, 5 is the only common factor. So, HCF of 5, 15, 25 is 5.

## What is the HCF of 18 and 24?

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 9 12 and 15?

The GCF or greatest common factor is the largest positive integer that will divide into each number evenly. For example, the greatest common factor of 9 and 12 would be 15.

## What is the LCM of 15 and 20?

Least common multiple (LCM) of 15 and 20 is 60.

## What is the highest common factor of 4 and 15?

Greatest common factor (GCF) of 4 and 15 is 1.

## What is the HCF of 9 15 and 24?

The GCF is the highest number that is a factor of all three of our “test subject numbers”. Ok, now let’s find what is common. There are 2s in 24 but not in 9 or 15, so there are no 2s in our GCF. There is one 3 in 24 and in 15 and two in 9 – so one 3 is common to all three numbers.

## What is the LCM for 15 and 10?

Least common multiple (LCM) of 10 and 15 is 30.
