Given numbers are 398, 900, 855, 218

The list of prime factors of all numbers are

Prime factors of 398 are 2 x 199

Prime factors of 900 are 2 x 2 x 3 x 3 x 5 x 5

Prime factors of 855 are 3 x 3 x 5 x 19

Prime factors of 218 are 2 x 109

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

Given numbers are 398, 900, 855, 218

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

Apply this formula for all numbers.

Step1:

LCM(398, 900) = 179100

GCD(398, 900) = ( 398 x 900 ) / 179100

= 398 / 900

= 398

Step2:

LCM(2, 855) = 1710

GCD(2, 855) = ( 2 x 855 ) / 1710

= 2 / 855

= 2

Step3:

LCM(1, 218) = 218

GCD(1, 218) = ( 1 x 218 ) / 218

= 1 / 218

= 1

So, Greatest Common Divisor of 398, 900, 855, 218 is 1
