How do you explain greatest common factor?

When we find all the factors of two or more numbers, and some factors are the same (“common”), then the largest of those common factors is the Greatest Common Factor. Example: the GCF of 12 and 16 is 4, because 1, 2 and 4 are common factors of both 12 and 16, and 4 is the greatest of them.

What is the greatest common factor in 30?

The prime factors of 30 are 2 x 3 x 5. The prime factors they have in common are 3 x 5. 3 x 5 = 15. The greatest common factor is 15.

What is the GCF of 10 and 20 and 30?

There are 4 common factors of 10, 20 and 30, that are 1, 2, 10, and 5. Therefore, the highest common factor of 10, 20 and 30 is 10.

What is GCF in math example?

The greatest common factor (GCF) of a set of numbers is the largest factor that all the numbers share. For example, 12, 20, and 24 have two common factors: 2 and 4.

What is the greatest common factor of 12 and 30?

6
GCF of 12 and 30 by Listing Common Factors Therefore, the greatest common factor of 12 and 30 is 6.

What is the greatest common factor of 30 48 and 2?

Hence, the GCF of 30 and 48 is 2 × 3 = 6.

What is the common factor of 10?

Factor of 10 = 1, 2, 5 and 10. Factor of 15 = 1, 3, 5 and 15. Therefore, common factors of 10 and 15 = 1 and 5.

What is the greatest factor of 10 30 and 45?

5
The GCF of 10, 30, and 45 is 5. ∴ The greatest number that divides 10, 30, and 45 is 5.

What is the LCM of 10 and 30?

30
Answer: LCM of 10 and 30 is 30.

What is the greatest factor?

The greatest common factor is the largest whole number that is a factor of the two given whole numbers. In other words, it is the largest number that can be divided evenly into the two given numbers.

What is the greatest common factor of24 and 30?

Answer: GCF of 24 and 30 is 6.

What is the GCF of 10?

To calculate the greatest common factor (GCF) of 10 and 15, we need to factor each number (factors of 10 = 1, 2, 5, 10; factors of 15 = 1, 3, 5, 15) and choose the greatest factor that exactly divides both 10 and 15, i.e., 5.
