Given numbers are 798, 351, 438, 791

The list of prime factors of all numbers are

Prime factors of 798 are 2 x 3 x 7 x 19

Prime factors of 351 are 3 x 3 x 3 x 13

Prime factors of 438 are 2 x 3 x 73

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 798, 351, 438, 791

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

Apply this formula for all numbers.

Step1:

LCM(798, 351) = 93366

GCD(798, 351) = ( 798 x 351 ) / 93366

= 798 / 351

= 798

Step2:

LCM(3, 438) = 438

GCD(3, 438) = ( 3 x 438 ) / 438

= 3 / 438

= 3

Step3:

LCM(3, 791) = 2373

GCD(3, 791) = ( 3 x 791 ) / 2373

= 3 / 791

= 3

So, Greatest Common Divisor of 798, 351, 438, 791 is 1
