Given numbers are 708, 657, 851, 780

The list of prime factors of all numbers are

Prime factors of 708 are 2 x 2 x 3 x 59

Prime factors of 657 are 3 x 3 x 73

Prime factors of 851 are 23 x 37

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

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

Given numbers are 708, 657, 851, 780

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

Apply this formula for all numbers.

Step1:

LCM(708, 657) = 155052

GCD(708, 657) = ( 708 x 657 ) / 155052

= 708 / 657

= 708

Step2:

LCM(3, 851) = 2553

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

= 3 / 851

= 3

Step3:

LCM(1, 780) = 780

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

= 1 / 780

= 1

So, Greatest Common Divisor of 708, 657, 851, 780 is 1
