Given numbers are 319, 780, 272, 456

The list of prime factors of all numbers are

Prime factors of 319 are 11 x 29

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

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

Prime factors of 456 are 2 x 2 x 2 x 3 x 19

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

Given numbers are 319, 780, 272, 456

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

Apply this formula for all numbers.

Step1:

LCM(319, 780) = 248820

GCD(319, 780) = ( 319 x 780 ) / 248820

= 319 / 780

= 319

Step2:

LCM(1, 272) = 272

GCD(1, 272) = ( 1 x 272 ) / 272

= 1 / 272

= 1

Step3:

LCM(1, 456) = 456

GCD(1, 456) = ( 1 x 456 ) / 456

= 1 / 456

= 1

So, Greatest Common Divisor of 319, 780, 272, 456 is 1
