Given numbers are 655, 451, 216, 630

The list of prime factors of all numbers are

Prime factors of 655 are 5 x 131

Prime factors of 451 are 11 x 41

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

Prime factors of 630 are 2 x 3 x 3 x 5 x 7

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

Given numbers are 655, 451, 216, 630

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

Apply this formula for all numbers.

Step1:

LCM(655, 451) = 295405

GCD(655, 451) = ( 655 x 451 ) / 295405

= 655 / 451

= 655

Step2:

LCM(1, 216) = 216

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

= 1 / 216

= 1

Step3:

LCM(1, 630) = 630

GCD(1, 630) = ( 1 x 630 ) / 630

= 1 / 630

= 1

So, Greatest Common Divisor of 655, 451, 216, 630 is 1
