Given numbers are 561, 120, 277, 124

The list of prime factors of all numbers are

Prime factors of 561 are 3 x 11 x 17

Prime factors of 120 are 2 x 2 x 2 x 3 x 5

Prime factors of 277 are 277

Prime factors of 124 are 2 x 2 x 31

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

Given numbers are 561, 120, 277, 124

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

Apply this formula for all numbers.

Step1:

LCM(561, 120) = 22440

GCD(561, 120) = ( 561 x 120 ) / 22440

= 561 / 120

= 561

Step2:

LCM(3, 277) = 831

GCD(3, 277) = ( 3 x 277 ) / 831

= 3 / 277

= 3

Step3:

LCM(1, 124) = 124

GCD(1, 124) = ( 1 x 124 ) / 124

= 1 / 124

= 1

So, Greatest Common Divisor of 561, 120, 277, 124 is 1
