Given numbers are 447, 480, 769, 455

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 769 are 769

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 447, 480, 769, 455

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, 769) = 2307

GCD(3, 769) = ( 3 x 769 ) / 2307

= 3 / 769

= 3

Step3:

LCM(1, 455) = 455

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

= 1 / 455

= 1

So, Greatest Common Divisor of 447, 480, 769, 455 is 1
