Given numbers are 418, 640, 287, 637

The list of prime factors of all numbers are

Prime factors of 418 are 2 x 11 x 19

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

Prime factors of 287 are 7 x 41

Prime factors of 637 are 7 x 7 x 13

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

Given numbers are 418, 640, 287, 637

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

Apply this formula for all numbers.

Step1:

LCM(418, 640) = 133760

GCD(418, 640) = ( 418 x 640 ) / 133760

= 418 / 640

= 418

Step2:

LCM(2, 287) = 574

GCD(2, 287) = ( 2 x 287 ) / 574

= 2 / 287

= 2

Step3:

LCM(1, 637) = 637

GCD(1, 637) = ( 1 x 637 ) / 637

= 1 / 637

= 1

So, Greatest Common Divisor of 418, 640, 287, 637 is 1
