Given numbers are 638, 476, 281, 216

The list of prime factors of all numbers are

Prime factors of 638 are 2 x 11 x 29

Prime factors of 476 are 2 x 2 x 7 x 17

Prime factors of 281 are 281

Prime factors of 216 are 2 x 2 x 2 x 3 x 3 x 3

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

Given numbers are 638, 476, 281, 216

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

Apply this formula for all numbers.

Step1:

LCM(638, 476) = 151844

GCD(638, 476) = ( 638 x 476 ) / 151844

= 638 / 476

= 638

Step2:

LCM(2, 281) = 562

GCD(2, 281) = ( 2 x 281 ) / 562

= 2 / 281

= 2

Step3:

LCM(1, 216) = 216

GCD(1, 216) = ( 1 x 216 ) / 216

= 1 / 216

= 1

So, Greatest Common Divisor of 638, 476, 281, 216 is 1
