Given numbers are 640, 621, 47, 277

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 621 are 3 x 3 x 3 x 23

Prime factors of 47 are 47

Prime factors of 277 are 277

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

Given numbers are 640, 621, 47, 277

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

Apply this formula for all numbers.

Step1:

LCM(640, 621) = 397440

GCD(640, 621) = ( 640 x 621 ) / 397440

= 640 / 621

= 640

Step2:

LCM(1, 47) = 47

GCD(1, 47) = ( 1 x 47 ) / 47

= 1 / 47

= 1

Step3:

LCM(1, 277) = 277

GCD(1, 277) = ( 1 x 277 ) / 277

= 1 / 277

= 1

So, Greatest Common Divisor of 640, 621, 47, 277 is 1
