5

FAQs on GCF of 10 and 15 The GCF of 10 and 15 is 5. 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.

## What is the greatest common factor of 20 20 and 15?

Therefore, the GCF of 15 and 20 is 5. Example 2: Find the GCF of 15 and 20, if their LCM is 60. Therefore, the greatest common factor of 15 and 20 is 5.

**What is the greatest common factor of 10 20 and 16?**

As you can see when you list out the factors of each number, 2 is the greatest number that 10, 16, and 20 divides into.

**What is the greatest common factor of 10 15 and 25?**

Like, the GCF of 10,15, and 25 is 5.

### What is the GCF of 4 and 10?

2

Answer: GCF of 4 and 10 is 2.

### What is the GCF of 24 and 18?

6

The greatest common factor is the greatest factor that divides both numbers. To find the greatest common factor, first list the prime factors of each number. 18 and 24 share one 2 and one 3 in common. We multiply them to get the GCF, so 2 * 3 = 6 is the GCF of 18 and 24.

**What is the GCF of 5 15 and 25?**

GCF of 15 and 25 by Prime Factorization As visible, 15 and 25 have only one common prime factor i.e. 5. Hence, the GCF of 15 and 25 is 5.

**What is the HCF of 5 and 9?**

1

What is the HCF of 5 and 9? The HCF of 5 and 9 is 1. To calculate the Highest common factor (HCF) of 5 and 9, we need to factor each number (factors of 5 = 1, 5; factors of 9 = 1, 3, 9) and choose the highest factor that exactly divides both 5 and 9, i.e., 1.

#### What is the GCF of 10,12 and 15?

It is not difficult to see that the ‘Greatest Common Factor’ or ‘Divisor’ for 10, 12 and 15 is 1. The GCF is the largest common positive integer that divides all the numbers (10,12,15) without a remainder. The GCF is also known as: Greatest common divisor (gcd);

#### What are the highest common factors of 10 and 15?

**What are the common multiples of 10 and 15?**

* The multiples of 10 are 10, 20, 30 * The multiples of 15 are 15, 30 Because 30 is the first number to appear on both lists of multiples, 30 is the LCM of 5, 10 and 15. Quote of the day…

**How do you factor out GCF?**

To factor out the GCF in an expression like the one above, first find the GCF of all of the expression’s terms. GCF = 3x. Next, write the GCF on the left of a set of parentheses: 3x( ) Next, divide each term from the original expression (3x 3+27x 2+9x ) by the GCF (3x), then write it in the parenthesis.
