Given numbers are 615, 168, 902, 189

The list of prime factors of all numbers are

Prime factors of 615 are 3 x 5 x 41

Prime factors of 168 are 2 x 2 x 2 x 3 x 7

Prime factors of 902 are 2 x 11 x 41

Prime factors of 189 are 3 x 3 x 3 x 7

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

Given numbers are 615, 168, 902, 189

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

Apply this formula for all numbers.

Step1:

LCM(615, 168) = 34440

GCD(615, 168) = ( 615 x 168 ) / 34440

= 615 / 168

= 615

Step2:

LCM(3, 902) = 2706

GCD(3, 902) = ( 3 x 902 ) / 2706

= 3 / 902

= 3

Step3:

LCM(1, 189) = 189

GCD(1, 189) = ( 1 x 189 ) / 189

= 1 / 189

= 1

So, Greatest Common Divisor of 615, 168, 902, 189 is 1
