Given numbers are 789, 780, 709, 627

The list of prime factors of all numbers are

Prime factors of 789 are 3 x 263

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

Prime factors of 709 are 709

Prime factors of 627 are 3 x 11 x 19

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

Given numbers are 789, 780, 709, 627

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

Apply this formula for all numbers.

Step1:

LCM(789, 780) = 205140

GCD(789, 780) = ( 789 x 780 ) / 205140

= 789 / 780

= 789

Step2:

LCM(3, 709) = 2127

GCD(3, 709) = ( 3 x 709 ) / 2127

= 3 / 709

= 3

Step3:

LCM(1, 627) = 627

GCD(1, 627) = ( 1 x 627 ) / 627

= 1 / 627

= 1

So, Greatest Common Divisor of 789, 780, 709, 627 is 1
