Given numbers are 447, 384, 451, 921

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

Apply this formula for all numbers.

Step1:

LCM(447, 384) = 57216

GCD(447, 384) = ( 447 x 384 ) / 57216

= 447 / 384

= 447

Step2:

LCM(3, 451) = 1353

GCD(3, 451) = ( 3 x 451 ) / 1353

= 3 / 451

= 3

Step3:

LCM(1, 921) = 921

GCD(1, 921) = ( 1 x 921 ) / 921

= 1 / 921

= 1

So, Greatest Common Divisor of 447, 384, 451, 921 is 1
