Given numbers are 674, 420, 681, 763

The list of prime factors of all numbers are

Prime factors of 674 are 2 x 337

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 763 are 7 x 109

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

Given numbers are 674, 420, 681, 763

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

Apply this formula for all numbers.

Step1:

LCM(674, 420) = 141540

GCD(674, 420) = ( 674 x 420 ) / 141540

= 674 / 420

= 674

Step2:

LCM(2, 681) = 1362

GCD(2, 681) = ( 2 x 681 ) / 1362

= 2 / 681

= 2

Step3:

LCM(1, 763) = 763

GCD(1, 763) = ( 1 x 763 ) / 763

= 1 / 763

= 1

So, Greatest Common Divisor of 674, 420, 681, 763 is 1
