Given numbers are 420, 774, 751, 857

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 774 are 2 x 3 x 3 x 43

Prime factors of 751 are 751

Prime factors of 857 are 857

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

Given numbers are 420, 774, 751, 857

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

Apply this formula for all numbers.

Step1:

LCM(420, 774) = 54180

GCD(420, 774) = ( 420 x 774 ) / 54180

= 420 / 774

= 420

Step2:

LCM(6, 751) = 4506

GCD(6, 751) = ( 6 x 751 ) / 4506

= 6 / 751

= 6

Step3:

LCM(1, 857) = 857

GCD(1, 857) = ( 1 x 857 ) / 857

= 1 / 857

= 1

So, Greatest Common Divisor of 420, 774, 751, 857 is 1
