Given numbers are 990, 456, 286, 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 456 are 2 x 2 x 2 x 3 x 19

Prime factors of 286 are 2 x 11 x 13

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, 456, 286, 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, 456) = 75240

GCD(990, 456) = ( 990 x 456 ) / 75240

= 990 / 456

= 990

Step2:

LCM(6, 286) = 858

GCD(6, 286) = ( 6 x 286 ) / 858

= 6 / 286

= 6

Step3:

LCM(2, 615) = 1230

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

= 2 / 615

= 2

So, Greatest Common Divisor of 990, 456, 286, 615 is 1
