Given numbers are 287, 621, 72, 272

The list of prime factors of all numbers are

Prime factors of 287 are 7 x 41

Prime factors of 621 are 3 x 3 x 3 x 23

Prime factors of 72 are 2 x 2 x 2 x 3 x 3

Prime factors of 272 are 2 x 2 x 2 x 2 x 17

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

Given numbers are 287, 621, 72, 272

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

Apply this formula for all numbers.

Step1:

LCM(287, 621) = 178227

GCD(287, 621) = ( 287 x 621 ) / 178227

= 287 / 621

= 287

Step2:

LCM(1, 72) = 72

GCD(1, 72) = ( 1 x 72 ) / 72

= 1 / 72

= 1

Step3:

LCM(1, 272) = 272

GCD(1, 272) = ( 1 x 272 ) / 272

= 1 / 272

= 1

So, Greatest Common Divisor of 287, 621, 72, 272 is 1
