Given numbers are 138, 604, 90, 615

The list of prime factors of all numbers are

Prime factors of 138 are 2 x 3 x 23

Prime factors of 604 are 2 x 2 x 151

Prime factors of 90 are 2 x 3 x 3 x 5

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 138, 604, 90, 615

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

Apply this formula for all numbers.

Step1:

LCM(138, 604) = 41676

GCD(138, 604) = ( 138 x 604 ) / 41676

= 138 / 604

= 138

Step2:

LCM(2, 90) = 90

GCD(2, 90) = ( 2 x 90 ) / 90

= 2 / 90

= 2

Step3:

LCM(2, 615) = 1230

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

= 2 / 615

= 2

So, Greatest Common Divisor of 138, 604, 90, 615 is 1
