Given numbers are 780, 653, 286, 591

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 653 are 653

Prime factors of 286 are 2 x 11 x 13

Prime factors of 591 are 3 x 197

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

Given numbers are 780, 653, 286, 591

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

Apply this formula for all numbers.

Step1:

LCM(780, 653) = 509340

GCD(780, 653) = ( 780 x 653 ) / 509340

= 780 / 653

= 780

Step2:

LCM(1, 286) = 286

GCD(1, 286) = ( 1 x 286 ) / 286

= 1 / 286

= 1

Step3:

LCM(1, 591) = 591

GCD(1, 591) = ( 1 x 591 ) / 591

= 1 / 591

= 1

So, Greatest Common Divisor of 780, 653, 286, 591 is 1
