Given numbers are 447, 115, 483, 780

The list of prime factors of all numbers are

Prime factors of 447 are 3 x 149

Prime factors of 115 are 5 x 23

Prime factors of 483 are 3 x 7 x 23

Prime factors of 780 are 2 x 2 x 3 x 5 x 13

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

Given numbers are 447, 115, 483, 780

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

Apply this formula for all numbers.

Step1:

LCM(447, 115) = 51405

GCD(447, 115) = ( 447 x 115 ) / 51405

= 447 / 115

= 447

Step2:

LCM(1, 483) = 483

GCD(1, 483) = ( 1 x 483 ) / 483

= 1 / 483

= 1

Step3:

LCM(1, 780) = 780

GCD(1, 780) = ( 1 x 780 ) / 780

= 1 / 780

= 1

So, Greatest Common Divisor of 447, 115, 483, 780 is 1
