Given numbers are 791, 609, 220, 345

The list of prime factors of all numbers are

Prime factors of 791 are 7 x 113

Prime factors of 609 are 3 x 7 x 29

Prime factors of 220 are 2 x 2 x 5 x 11

Prime factors of 345 are 3 x 5 x 23

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

Given numbers are 791, 609, 220, 345

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

Apply this formula for all numbers.

Step1:

LCM(791, 609) = 68817

GCD(791, 609) = ( 791 x 609 ) / 68817

= 791 / 609

= 791

Step2:

LCM(7, 220) = 1540

GCD(7, 220) = ( 7 x 220 ) / 1540

= 7 / 220

= 7

Step3:

LCM(1, 345) = 345

GCD(1, 345) = ( 1 x 345 ) / 345

= 1 / 345

= 1

So, Greatest Common Divisor of 791, 609, 220, 345 is 1
