The list of prime factors of all numbers are

Prime factors of 778 are 2 x 389

Prime factors of 470 are 2 x 5 x 47

Prime factors of 791 are 7 x 113

Prime factors of 138 are 2 x 3 x 23

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

Given numbers are 778, 470, 791, 138

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

Apply this formula for all numbers.

Step1:

LCM(778, 470) = 182830

GCD(778, 470) = ( 778 x 470 ) / 182830

= 778 / 470

= 778

Step2:

LCM(2, 791) = 1582

GCD(2, 791) = ( 2 x 791 ) / 1582

= 2 / 791

= 2

Step3:

LCM(1, 138) = 138

GCD(1, 138) = ( 1 x 138 ) / 138

= 1 / 138

= 1

So, Greatest Common Divisor of 778, 470, 791, 138 is 1
