Question

What is GCF of 8,20 and 36

Answer 1

Answer:

Greatest common factor (GCF) of 36 and 8 is 4. We will now calculate the prime factors of 36 and 8, than find the greatest common factor (greatest common divisor (gcd)) of the numbers by matching the biggest common factor of 36 and 8.

Greatest common factor (GCF) of 20 and 36 is 4. We will now calculate the prime factors of 20 and 36, than find the greatest common factor (greatest common divisor (gcd)) of the numbers by matching the biggest common factor of 20 and 36.

Answer 2

The greatest common factor is 4.

To find,

GCF of 8,20 and 36

Solution:

• The factors of 8 = 1,2,4 and 8
• The factors of 20 = 1,2,4,5,10 and 20
• The factors of 36 = 1,2,3,4,6,9,12,18 and 36

Hence, the common factors are 1, 2 and 4.

Hence, the greatest common factor is 4.
