Given numbers are 648, 615, 22, 417

The list of prime factors of all numbers are

Prime factors of 648 are 2 x 2 x 2 x 3 x 3 x 3 x 3

Prime factors of 615 are 3 x 5 x 41

Prime factors of 22 are 2 x 11

Prime factors of 417 are 3 x 139

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

Given numbers are 648, 615, 22, 417

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

Apply this formula for all numbers.

Step1:

LCM(648, 615) = 132840

GCD(648, 615) = ( 648 x 615 ) / 132840

= 648 / 615

= 648

Step2:

LCM(3, 22) = 66

GCD(3, 22) = ( 3 x 22 ) / 66

= 3 / 22

= 3

Step3:

LCM(1, 417) = 417

GCD(1, 417) = ( 1 x 417 ) / 417

= 1 / 417

= 1

So, Greatest Common Divisor of 648, 615, 22, 417 is 1
