Given numbers are 684, 556, 677, 400

The list of prime factors of all numbers are

Prime factors of 684 are 2 x 2 x 3 x 3 x 19

Prime factors of 556 are 2 x 2 x 139

Prime factors of 677 are 677

Prime factors of 400 are 2 x 2 x 2 x 2 x 5 x 5

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

Given numbers are 684, 556, 677, 400

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

Apply this formula for all numbers.

Step1:

LCM(684, 556) = 95076

GCD(684, 556) = ( 684 x 556 ) / 95076

= 684 / 556

= 684

Step2:

LCM(4, 677) = 2708

GCD(4, 677) = ( 4 x 677 ) / 2708

= 4 / 677

= 4

Step3:

LCM(1, 400) = 400

GCD(1, 400) = ( 1 x 400 ) / 400

= 1 / 400

= 1

So, Greatest Common Divisor of 684, 556, 677, 400 is 1
