Given numbers are 642, 975, 806, 250

The list of prime factors of all numbers are

Prime factors of 642 are 2 x 3 x 107

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

Prime factors of 806 are 2 x 13 x 31

Prime factors of 250 are 2 x 5 x 5 x 5

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

Given numbers are 642, 975, 806, 250

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

Apply this formula for all numbers.

Step1:

LCM(642, 975) = 208650

GCD(642, 975) = ( 642 x 975 ) / 208650

= 642 / 975

= 642

Step2:

LCM(3, 806) = 2418

GCD(3, 806) = ( 3 x 806 ) / 2418

= 3 / 806

= 3

Step3:

LCM(1, 250) = 250

GCD(1, 250) = ( 1 x 250 ) / 250

= 1 / 250

= 1

So, Greatest Common Divisor of 642, 975, 806, 250 is 1
