Given numbers are 655, 617, 516, 120

The list of prime factors of all numbers are

Prime factors of 655 are 5 x 131

Prime factors of 617 are 617

Prime factors of 516 are 2 x 2 x 3 x 43

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

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

Given numbers are 655, 617, 516, 120

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

Apply this formula for all numbers.

Step1:

LCM(655, 617) = 404135

GCD(655, 617) = ( 655 x 617 ) / 404135

= 655 / 617

= 655

Step2:

LCM(1, 516) = 516

GCD(1, 516) = ( 1 x 516 ) / 516

= 1 / 516

= 1

Step3:

LCM(1, 120) = 120

GCD(1, 120) = ( 1 x 120 ) / 120

= 1 / 120

= 1

So, Greatest Common Divisor of 655, 617, 516, 120 is 1
