Given numbers are 636, 640, 121, 271

The list of prime factors of all numbers are

Prime factors of 636 are 2 x 2 x 3 x 53

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

Prime factors of 121 are 11 x 11

Prime factors of 271 are 271

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

Given numbers are 636, 640, 121, 271

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

Apply this formula for all numbers.

Step1:

LCM(636, 640) = 101760

GCD(636, 640) = ( 636 x 640 ) / 101760

= 636 / 640

= 636

Step2:

LCM(4, 121) = 484

GCD(4, 121) = ( 4 x 121 ) / 484

= 4 / 121

= 4

Step3:

LCM(1, 271) = 271

GCD(1, 271) = ( 1 x 271 ) / 271

= 1 / 271

= 1

So, Greatest Common Divisor of 636, 640, 121, 271 is 1
