Given numbers are 420, 493, 903, 677

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 493 are 17 x 29

Prime factors of 903 are 3 x 7 x 43

Prime factors of 677 are 677

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

Given numbers are 420, 493, 903, 677

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

Apply this formula for all numbers.

Step1:

LCM(420, 493) = 207060

GCD(420, 493) = ( 420 x 493 ) / 207060

= 420 / 493

= 420

Step2:

LCM(1, 903) = 903

GCD(1, 903) = ( 1 x 903 ) / 903

= 1 / 903

= 1

Step3:

LCM(1, 677) = 677

GCD(1, 677) = ( 1 x 677 ) / 677

= 1 / 677

= 1

So, Greatest Common Divisor of 420, 493, 903, 677 is 1
