Given numbers are 990, 718, 518, 615

The list of prime factors of all numbers are

Prime factors of 990 are 2 x 3 x 3 x 5 x 11

Prime factors of 718 are 2 x 359

Prime factors of 518 are 2 x 7 x 37

Prime factors of 615 are 3 x 5 x 41

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

Given numbers are 990, 718, 518, 615

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

Apply this formula for all numbers.

Step1:

LCM(990, 718) = 355410

GCD(990, 718) = ( 990 x 718 ) / 355410

= 990 / 718

= 990

Step2:

LCM(2, 518) = 518

GCD(2, 518) = ( 2 x 518 ) / 518

= 2 / 518

= 2

Step3:

LCM(2, 615) = 1230

GCD(2, 615) = ( 2 x 615 ) / 1230

= 2 / 615

= 2

So, Greatest Common Divisor of 990, 718, 518, 615 is 1
