Given numbers are 615, 254, 780, 729

The list of prime factors of all numbers are

Prime factors of 615 are 3 x 5 x 41

Prime factors of 254 are 2 x 127

Prime factors of 780 are 2 x 2 x 3 x 5 x 13

Prime factors of 729 are 3 x 3 x 3 x 3 x 3 x 3

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

Given numbers are 615, 254, 780, 729

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

Apply this formula for all numbers.

Step1:

LCM(615, 254) = 156210

GCD(615, 254) = ( 615 x 254 ) / 156210

= 615 / 254

= 615

Step2:

LCM(1, 780) = 780

GCD(1, 780) = ( 1 x 780 ) / 780

= 1 / 780

= 1

Step3:

LCM(1, 729) = 729

GCD(1, 729) = ( 1 x 729 ) / 729

= 1 / 729

= 1

So, Greatest Common Divisor of 615, 254, 780, 729 is 1
