Given numbers are 770, 634, 780, 943

The list of prime factors of all numbers are

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

Prime factors of 634 are 2 x 317

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

Prime factors of 943 are 23 x 41

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

Given numbers are 770, 634, 780, 943

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

Apply this formula for all numbers.

Step1:

LCM(770, 634) = 244090

GCD(770, 634) = ( 770 x 634 ) / 244090

= 770 / 634

= 770

Step2:

LCM(2, 780) = 780

GCD(2, 780) = ( 2 x 780 ) / 780

= 2 / 780

= 2

Step3:

LCM(2, 943) = 1886

GCD(2, 943) = ( 2 x 943 ) / 1886

= 2 / 943

= 2

So, Greatest Common Divisor of 770, 634, 780, 943 is 1
