Given numbers are 447, 480, 212, 648

The list of prime factors of all numbers are

Prime factors of 447 are 3 x 149

Prime factors of 480 are 2 x 2 x 2 x 2 x 2 x 3 x 5

Prime factors of 212 are 2 x 2 x 53

Prime factors of 648 are 2 x 2 x 2 x 3 x 3 x 3 x 3

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

Given numbers are 447, 480, 212, 648

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

Apply this formula for all numbers.

Step1:

LCM(447, 480) = 71520

GCD(447, 480) = ( 447 x 480 ) / 71520

= 447 / 480

= 447

Step2:

LCM(3, 212) = 636

GCD(3, 212) = ( 3 x 212 ) / 636

= 3 / 212

= 3

Step3:

LCM(1, 648) = 648

GCD(1, 648) = ( 1 x 648 ) / 648

= 1 / 648

= 1

So, Greatest Common Divisor of 447, 480, 212, 648 is 1
