Given numbers are 642, 747, 228, 931

The list of prime factors of all numbers are

Prime factors of 642 are 2 x 3 x 107

Prime factors of 747 are 3 x 3 x 83

Prime factors of 228 are 2 x 2 x 3 x 19

Prime factors of 931 are 7 x 7 x 19

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

Given numbers are 642, 747, 228, 931

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

Apply this formula for all numbers.

Step1:

LCM(642, 747) = 159858

GCD(642, 747) = ( 642 x 747 ) / 159858

= 642 / 747

= 642

Step2:

LCM(3, 228) = 228

GCD(3, 228) = ( 3 x 228 ) / 228

= 3 / 228

= 3

Step3:

LCM(3, 931) = 2793

GCD(3, 931) = ( 3 x 931 ) / 2793

= 3 / 931

= 3

So, Greatest Common Divisor of 642, 747, 228, 931 is 1
