Given numbers are 756, 114, 561, 421

The list of prime factors of all numbers are

Prime factors of 756 are 2 x 2 x 3 x 3 x 3 x 7

Prime factors of 114 are 2 x 3 x 19

Prime factors of 561 are 3 x 11 x 17

Prime factors of 421 are 421

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

Given numbers are 756, 114, 561, 421

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

Apply this formula for all numbers.

Step1:

LCM(756, 114) = 14364

GCD(756, 114) = ( 756 x 114 ) / 14364

= 756 / 114

= 756

Step2:

LCM(6, 561) = 1122

GCD(6, 561) = ( 6 x 561 ) / 1122

= 6 / 561

= 6

Step3:

LCM(3, 421) = 1263

GCD(3, 421) = ( 3 x 421 ) / 1263

= 3 / 421

= 3

So, Greatest Common Divisor of 756, 114, 561, 421 is 1
