Given numbers are 515, 117, 405, 124

The list of prime factors of all numbers are

Prime factors of 515 are 5 x 103

Prime factors of 117 are 3 x 3 x 13

Prime factors of 405 are 3 x 3 x 3 x 3 x 5

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 515, 117, 405, 124

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

Apply this formula for all numbers.

Step1:

LCM(515, 117) = 60255

GCD(515, 117) = ( 515 x 117 ) / 60255

= 515 / 117

= 515

Step2:

LCM(1, 405) = 405

GCD(1, 405) = ( 1 x 405 ) / 405

= 1 / 405

= 1

Step3:

LCM(1, 124) = 124

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

= 1 / 124

= 1

So, Greatest Common Divisor of 515, 117, 405, 124 is 1
