Given numbers are 642, 388, 416, 975

The list of prime factors of all numbers are

Prime factors of 642 are 2 x 3 x 107

Prime factors of 388 are 2 x 2 x 97

Prime factors of 416 are 2 x 2 x 2 x 2 x 2 x 13

Prime factors of 975 are 3 x 5 x 5 x 13

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

Given numbers are 642, 388, 416, 975

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

Apply this formula for all numbers.

Step1:

LCM(642, 388) = 124548

GCD(642, 388) = ( 642 x 388 ) / 124548

= 642 / 388

= 642

Step2:

LCM(2, 416) = 416

GCD(2, 416) = ( 2 x 416 ) / 416

= 2 / 416

= 2

Step3:

LCM(2, 975) = 1950

GCD(2, 975) = ( 2 x 975 ) / 1950

= 2 / 975

= 2

So, Greatest Common Divisor of 642, 388, 416, 975 is 1
