Given numbers are 680, 172, 681, 940

The list of prime factors of all numbers are

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

Prime factors of 172 are 2 x 2 x 43

Prime factors of 681 are 3 x 227

Prime factors of 940 are 2 x 2 x 5 x 47

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

Given numbers are 680, 172, 681, 940

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

Apply this formula for all numbers.

Step1:

LCM(680, 172) = 29240

GCD(680, 172) = ( 680 x 172 ) / 29240

= 680 / 172

= 680

Step2:

LCM(4, 681) = 2724

GCD(4, 681) = ( 4 x 681 ) / 2724

= 4 / 681

= 4

Step3:

LCM(1, 940) = 940

GCD(1, 940) = ( 1 x 940 ) / 940

= 1 / 940

= 1

So, Greatest Common Divisor of 680, 172, 681, 940 is 1
