Given numbers are 615, 645, 156, 730

The list of prime factors of all numbers are

Prime factors of 615 are 3 x 5 x 41

Prime factors of 645 are 3 x 5 x 43

Prime factors of 156 are 2 x 2 x 3 x 13

Prime factors of 730 are 2 x 5 x 73

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

Given numbers are 615, 645, 156, 730

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

Apply this formula for all numbers.

Step1:

LCM(615, 645) = 26445

GCD(615, 645) = ( 615 x 645 ) / 26445

= 615 / 645

= 615

Step2:

LCM(15, 156) = 780

GCD(15, 156) = ( 15 x 156 ) / 780

= 15 / 156

= 15

Step3:

LCM(3, 730) = 2190

GCD(3, 730) = ( 3 x 730 ) / 2190

= 3 / 730

= 3

So, Greatest Common Divisor of 615, 645, 156, 730 is 1
