Given numbers are 420, 985, 577, 676

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 985 are 5 x 197

Prime factors of 577 are 577

Prime factors of 676 are 2 x 2 x 13 x 13

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

Given numbers are 420, 985, 577, 676

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

Apply this formula for all numbers.

Step1:

LCM(420, 985) = 82740

GCD(420, 985) = ( 420 x 985 ) / 82740

= 420 / 985

= 420

Step2:

LCM(5, 577) = 2885

GCD(5, 577) = ( 5 x 577 ) / 2885

= 5 / 577

= 5

Step3:

LCM(1, 676) = 676

GCD(1, 676) = ( 1 x 676 ) / 676

= 1 / 676

= 1

So, Greatest Common Divisor of 420, 985, 577, 676 is 1
