Given numbers are 636, 216, 287, 455

The list of prime factors of all numbers are

Prime factors of 636 are 2 x 2 x 3 x 53

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

Prime factors of 287 are 7 x 41

Prime factors of 455 are 5 x 7 x 13

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

Given numbers are 636, 216, 287, 455

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

Apply this formula for all numbers.

Step1:

LCM(636, 216) = 11448

GCD(636, 216) = ( 636 x 216 ) / 11448

= 636 / 216

= 636

Step2:

LCM(12, 287) = 3444

GCD(12, 287) = ( 12 x 287 ) / 3444

= 12 / 287

= 12

Step3:

LCM(1, 455) = 455

GCD(1, 455) = ( 1 x 455 ) / 455

= 1 / 455

= 1

So, Greatest Common Divisor of 636, 216, 287, 455 is 1
