Given numbers are 420, 352, 972, 641

The list of prime factors of all numbers are

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

Prime factors of 352 are 2 x 2 x 2 x 2 x 2 x 11

Prime factors of 972 are 2 x 2 x 3 x 3 x 3 x 3 x 3

Prime factors of 641 are 641

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

Given numbers are 420, 352, 972, 641

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

Apply this formula for all numbers.

Step1:

LCM(420, 352) = 36960

GCD(420, 352) = ( 420 x 352 ) / 36960

= 420 / 352

= 420

Step2:

LCM(4, 972) = 972

GCD(4, 972) = ( 4 x 972 ) / 972

= 4 / 972

= 4

Step3:

LCM(4, 641) = 2564

GCD(4, 641) = ( 4 x 641 ) / 2564

= 4 / 641

= 4

So, Greatest Common Divisor of 420, 352, 972, 641 is 1
