Given numbers are 398, 987, 485, 456

The list of prime factors of all numbers are

Prime factors of 398 are 2 x 199

Prime factors of 987 are 3 x 7 x 47

Prime factors of 485 are 5 x 97

Prime factors of 456 are 2 x 2 x 2 x 3 x 19

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

Given numbers are 398, 987, 485, 456

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

Apply this formula for all numbers.

Step1:

LCM(398, 987) = 392826

GCD(398, 987) = ( 398 x 987 ) / 392826

= 398 / 987

= 398

Step2:

LCM(1, 485) = 485

GCD(1, 485) = ( 1 x 485 ) / 485

= 1 / 485

= 1

Step3:

LCM(1, 456) = 456

GCD(1, 456) = ( 1 x 456 ) / 456

= 1 / 456

= 1

So, Greatest Common Divisor of 398, 987, 485, 456 is 1
