Given numbers are 447, 276, 684, 728

The list of prime factors of all numbers are

Prime factors of 447 are 3 x 149

Prime factors of 276 are 2 x 2 x 3 x 23

Prime factors of 684 are 2 x 2 x 3 x 3 x 19

Prime factors of 728 are 2 x 2 x 2 x 7 x 13

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

Given numbers are 447, 276, 684, 728

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

Apply this formula for all numbers.

Step1:

LCM(447, 276) = 41124

GCD(447, 276) = ( 447 x 276 ) / 41124

= 447 / 276

= 447

Step2:

LCM(3, 684) = 684

GCD(3, 684) = ( 3 x 684 ) / 684

= 3 / 684

= 3

Step3:

LCM(3, 728) = 2184

GCD(3, 728) = ( 3 x 728 ) / 2184

= 3 / 728

= 3

So, Greatest Common Divisor of 447, 276, 684, 728 is 1
