Given numbers are 478, 516, 431, 198

The list of prime factors of all numbers are

Prime factors of 478 are 2 x 239

Prime factors of 516 are 2 x 2 x 3 x 43

Prime factors of 431 are 431

Prime factors of 198 are 2 x 3 x 3 x 11

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

Given numbers are 478, 516, 431, 198

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

Apply this formula for all numbers.

Step1:

LCM(478, 516) = 123324

GCD(478, 516) = ( 478 x 516 ) / 123324

= 478 / 516

= 478

Step2:

LCM(2, 431) = 862

GCD(2, 431) = ( 2 x 431 ) / 862

= 2 / 431

= 2

Step3:

LCM(1, 198) = 198

GCD(1, 198) = ( 1 x 198 ) / 198

= 1 / 198

= 1

So, Greatest Common Divisor of 478, 516, 431, 198 is 1
