Given numbers are 398, 623, 631, 360

The list of prime factors of all numbers are

Prime factors of 398 are 2 x 199

Prime factors of 623 are 7 x 89

Prime factors of 631 are 631

Prime factors of 360 are 2 x 2 x 2 x 3 x 3 x 5

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

Given numbers are 398, 623, 631, 360

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

Apply this formula for all numbers.

Step1:

LCM(398, 623) = 247954

GCD(398, 623) = ( 398 x 623 ) / 247954

= 398 / 623

= 398

Step2:

LCM(1, 631) = 631

GCD(1, 631) = ( 1 x 631 ) / 631

= 1 / 631

= 1

Step3:

LCM(1, 360) = 360

GCD(1, 360) = ( 1 x 360 ) / 360

= 1 / 360

= 1

So, Greatest Common Divisor of 398, 623, 631, 360 is 1
