Given numbers are 780, 615, 567, 304

The list of prime factors of all numbers are

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

Prime factors of 615 are 3 x 5 x 41

Prime factors of 567 are 3 x 3 x 3 x 3 x 7

Prime factors of 304 are 2 x 2 x 2 x 2 x 19

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

Given numbers are 780, 615, 567, 304

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

Apply this formula for all numbers.

Step1:

LCM(780, 615) = 31980

GCD(780, 615) = ( 780 x 615 ) / 31980

= 780 / 615

= 780

Step2:

LCM(15, 567) = 2835

GCD(15, 567) = ( 15 x 567 ) / 2835

= 15 / 567

= 15

Step3:

LCM(3, 304) = 912

GCD(3, 304) = ( 3 x 304 ) / 912

= 3 / 304

= 3

So, Greatest Common Divisor of 780, 615, 567, 304 is 1
