What is the GCF of 28 and 24?

4
Answer: GCF of 24 and 28 is 4. Explanation: The GCF of two non-zero integers, x(24) and y(28), is the greatest positive integer m(4) that divides both x(24) and y(28) without any remainder.

#### How do you solve for GCF?

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 28 and 14?

### What is the GCF of 24 and 28?

Answer: GCF of 24 and 28 is 4. Explanation: The GCF of two non-zero integers, x(24) and y(28), is the greatest positive integer m(4) that divides both x(24) and y(28) without any remainder.

What is the GCF of 2 numbers?

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. The largest is 4, so we say that the GCF of 12, 20, and 24 is 4.

What is the GCF of 28 42 and 98?

Greatest common factor (GCF) of 28 and 42 is 14.. GCF(28,42) = 14. We will now calculate the prime factors of 28 and 42, than find the greatest common factor (greatest common divisor (gcd)) of the numbers by matching the biggest common factor of 28 and 42.

#### How do you calculate GCF?

Factor each number completely into its prime numbers. A prime number is number greater than 1 that has no factors but itself.

• Identify any common prime factors. Pick out any prime numbers between the set that are the same.
• Calculate: If there are no common factors then the greatest common factor is 1.
• To demonstrate this method,study this example.
• What is the greatest common factor (GCF) of 28 and 70?

The biggest common factor number is the GCF number. So the greatest common factor 28 and 70 is 14. Also check out the Least Common Multiple of 28 and 70

What is the greatest common factor of 28 and 64?
