Given numbers are 780, 725, 138, 791

The list of prime factors of all numbers are

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

Prime factors of 725 are 5 x 5 x 29

Prime factors of 138 are 2 x 3 x 23

Prime factors of 791 are 7 x 113

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

Given numbers are 780, 725, 138, 791

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

Apply this formula for all numbers.

Step1:

LCM(780, 725) = 113100

GCD(780, 725) = ( 780 x 725 ) / 113100

= 780 / 725

= 780

Step2:

LCM(5, 138) = 690

GCD(5, 138) = ( 5 x 138 ) / 690

= 5 / 138

= 5

Step3:

LCM(1, 791) = 791

GCD(1, 791) = ( 1 x 791 ) / 791

= 1 / 791

= 1

So, Greatest Common Divisor of 780, 725, 138, 791 is 1
