Given numbers are 478, 168, 798, 515

The list of prime factors of all numbers are

Prime factors of 478 are 2 x 239

Prime factors of 168 are 2 x 2 x 2 x 3 x 7

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

Prime factors of 515 are 5 x 103

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

Given numbers are 478, 168, 798, 515

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

Apply this formula for all numbers.

Step1:

LCM(478, 168) = 40152

GCD(478, 168) = ( 478 x 168 ) / 40152

= 478 / 168

= 478

Step2:

LCM(2, 798) = 798

GCD(2, 798) = ( 2 x 798 ) / 798

= 2 / 798

= 2

Step3:

LCM(2, 515) = 1030

GCD(2, 515) = ( 2 x 515 ) / 1030

= 2 / 515

= 2

So, Greatest Common Divisor of 478, 168, 798, 515 is 1
