Given numbers are 791, 630, 742, 173

The list of prime factors of all numbers are

Prime factors of 791 are 7 x 113

Prime factors of 630 are 2 x 3 x 3 x 5 x 7

Prime factors of 742 are 2 x 7 x 53

Prime factors of 173 are 173

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

Given numbers are 791, 630, 742, 173

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

Apply this formula for all numbers.

Step1:

LCM(791, 630) = 71190

GCD(791, 630) = ( 791 x 630 ) / 71190

= 791 / 630

= 791

Step2:

LCM(7, 742) = 742

GCD(7, 742) = ( 7 x 742 ) / 742

= 7 / 742

= 7

Step3:

LCM(7, 173) = 1211

GCD(7, 173) = ( 7 x 173 ) / 1211

= 7 / 173

= 7

So, Greatest Common Divisor of 791, 630, 742, 173 is 1
