Given numbers are 277, 676, 839, 420

The list of prime factors of all numbers are

Prime factors of 277 are 277

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

Prime factors of 839 are 839

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

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

Given numbers are 277, 676, 839, 420

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

Apply this formula for all numbers.

Step1:

LCM(277, 676) = 187252

GCD(277, 676) = ( 277 x 676 ) / 187252

= 277 / 676

= 277

Step2:

LCM(1, 839) = 839

GCD(1, 839) = ( 1 x 839 ) / 839

= 1 / 839

= 1

Step3:

LCM(1, 420) = 420

GCD(1, 420) = ( 1 x 420 ) / 420

= 1 / 420

= 1

So, Greatest Common Divisor of 277, 676, 839, 420 is 1
