Given numbers are 561, 756, 349, 151

The list of prime factors of all numbers are

Prime factors of 561 are 3 x 11 x 17

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

Prime factors of 349 are 349

Prime factors of 151 are 151

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

Given numbers are 561, 756, 349, 151

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

Apply this formula for all numbers.

Step1:

LCM(561, 756) = 141372

GCD(561, 756) = ( 561 x 756 ) / 141372

= 561 / 756

= 561

Step2:

LCM(3, 349) = 1047

GCD(3, 349) = ( 3 x 349 ) / 1047

= 3 / 349

= 3

Step3:

LCM(1, 151) = 151

GCD(1, 151) = ( 1 x 151 ) / 151

= 1 / 151

= 1

So, Greatest Common Divisor of 561, 756, 349, 151 is 1
