Given numbers are 615, 120, 841, 637

The list of prime factors of all numbers are

Prime factors of 615 are 3 x 5 x 41

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

Prime factors of 841 are 29 x 29

Prime factors of 637 are 7 x 7 x 13

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

Given numbers are 615, 120, 841, 637

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

Apply this formula for all numbers.

Step1:

LCM(615, 120) = 4920

GCD(615, 120) = ( 615 x 120 ) / 4920

= 615 / 120

= 615

Step2:

LCM(15, 841) = 12615

GCD(15, 841) = ( 15 x 841 ) / 12615

= 15 / 841

= 15

Step3:

LCM(1, 637) = 637

GCD(1, 637) = ( 1 x 637 ) / 637

= 1 / 637

= 1

So, Greatest Common Divisor of 615, 120, 841, 637 is 1
