Given numbers are 228, 639, 680, 931

The list of prime factors of all numbers are

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

Prime factors of 639 are 3 x 3 x 71

Prime factors of 680 are 2 x 2 x 2 x 5 x 17

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 228, 639, 680, 931

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

Apply this formula for all numbers.

Step1:

LCM(228, 639) = 48564

GCD(228, 639) = ( 228 x 639 ) / 48564

= 228 / 639

= 228

Step2:

LCM(3, 680) = 2040

GCD(3, 680) = ( 3 x 680 ) / 2040

= 3 / 680

= 3

Step3:

LCM(1, 931) = 931

GCD(1, 931) = ( 1 x 931 ) / 931

= 1 / 931

= 1

So, Greatest Common Divisor of 228, 639, 680, 931 is 1
