Given numbers are 767, 851, 780, 770

The list of prime factors of all numbers are

Prime factors of 767 are 13 x 59

Prime factors of 851 are 23 x 37

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

Prime factors of 770 are 2 x 5 x 7 x 11

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

Given numbers are 767, 851, 780, 770

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

Apply this formula for all numbers.

Step1:

LCM(767, 851) = 652717

GCD(767, 851) = ( 767 x 851 ) / 652717

= 767 / 851

= 767

Step2:

LCM(1, 780) = 780

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

= 1 / 780

= 1

Step3:

LCM(1, 770) = 770

GCD(1, 770) = ( 1 x 770 ) / 770

= 1 / 770

= 1

So, Greatest Common Divisor of 767, 851, 780, 770 is 1
