Given numbers are 272, 395, 780, 609

The list of prime factors of all numbers are

Prime factors of 272 are 2 x 2 x 2 x 2 x 17

Prime factors of 395 are 5 x 79

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

Prime factors of 609 are 3 x 7 x 29

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

Given numbers are 272, 395, 780, 609

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

Apply this formula for all numbers.

Step1:

LCM(272, 395) = 107440

GCD(272, 395) = ( 272 x 395 ) / 107440

= 272 / 395

= 272

Step2:

LCM(1, 780) = 780

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

= 1 / 780

= 1

Step3:

LCM(1, 609) = 609

GCD(1, 609) = ( 1 x 609 ) / 609

= 1 / 609

= 1

So, Greatest Common Divisor of 272, 395, 780, 609 is 1
