Given numbers are 459, 780, 681, 851

The list of prime factors of all numbers are

Prime factors of 459 are 3 x 3 x 3 x 17

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

Prime factors of 681 are 3 x 227

Prime factors of 851 are 23 x 37

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

Given numbers are 459, 780, 681, 851

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

Apply this formula for all numbers.

Step1:

LCM(459, 780) = 119340

GCD(459, 780) = ( 459 x 780 ) / 119340

= 459 / 780

= 459

Step2:

LCM(3, 681) = 681

GCD(3, 681) = ( 3 x 681 ) / 681

= 3 / 681

= 3

Step3:

LCM(3, 851) = 2553

GCD(3, 851) = ( 3 x 851 ) / 2553

= 3 / 851

= 3

So, Greatest Common Divisor of 459, 780, 681, 851 is 1
