Given numbers are 659, 420, 615, 240

The list of prime factors of all numbers are

Prime factors of 659 are 659

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

Prime factors of 615 are 3 x 5 x 41

Prime factors of 240 are 2 x 2 x 2 x 2 x 3 x 5

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

Given numbers are 659, 420, 615, 240

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

Apply this formula for all numbers.

Step1:

LCM(659, 420) = 276780

GCD(659, 420) = ( 659 x 420 ) / 276780

= 659 / 420

= 659

Step2:

LCM(1, 615) = 615

GCD(1, 615) = ( 1 x 615 ) / 615

= 1 / 615

= 1

Step3:

LCM(1, 240) = 240

GCD(1, 240) = ( 1 x 240 ) / 240

= 1 / 240

= 1

So, Greatest Common Divisor of 659, 420, 615, 240 is 1
