Given numbers are 420, 681, 77, 718

The list of prime factors of all numbers are

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

Prime factors of 681 are 3 x 227

Prime factors of 77 are 7 x 11

Prime factors of 718 are 2 x 359

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

Given numbers are 420, 681, 77, 718

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

Apply this formula for all numbers.

Step1:

LCM(420, 681) = 95340

GCD(420, 681) = ( 420 x 681 ) / 95340

= 420 / 681

= 420

Step2:

LCM(3, 77) = 231

GCD(3, 77) = ( 3 x 77 ) / 231

= 3 / 77

= 3

Step3:

LCM(1, 718) = 718

GCD(1, 718) = ( 1 x 718 ) / 718

= 1 / 718

= 1

So, Greatest Common Divisor of 420, 681, 77, 718 is 1
