1, 3, 7, 21

GCD of numbers is the greatest common divisor

So, the GCD (94, 64, 21) = 1.

Given numbers are 94, 64, 21

The list of prime factors of all numbers are

Prime factors of 94 are 2 x 47

Prime factors of 64 are 2 x 2 x 2 x 2 x 2 x 2

Prime factors of 21 are 3 x 7

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 94, 64, 21

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(94, 64) = 3008

GCD(94, 64) = ( 94 x 64 ) / 3008

= 94 / 64

= 94

Step2:

LCM(2, 21) = 42

GCD(2, 21) = ( 2 x 21 ) / 42

= 2 / 21

= 2

So, Greatest Common Divisor of 94, 64, 21 is 1
