Given numbers are 640, 656, 100, 521

The list of prime factors of all numbers are

Prime factors of 640 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5

Prime factors of 656 are 2 x 2 x 2 x 2 x 41

Prime factors of 100 are 2 x 2 x 5 x 5

Prime factors of 521 are 521

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

Given numbers are 640, 656, 100, 521

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

Apply this formula for all numbers.

Step1:

LCM(640, 656) = 26240

GCD(640, 656) = ( 640 x 656 ) / 26240

= 640 / 656

= 640

Step2:

LCM(16, 100) = 400

GCD(16, 100) = ( 16 x 100 ) / 400

= 16 / 100

= 16

Step3:

LCM(4, 521) = 2084

GCD(4, 521) = ( 4 x 521 ) / 2084

= 4 / 521

= 4

So, Greatest Common Divisor of 640, 656, 100, 521 is 1
