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

Apply this formula for all numbers.

Step1:

LCM(975, 921) = 299325

GCD(975, 921) = ( 975 x 921 ) / 299325

= 975 / 921

= 975

Step2:

LCM(3, 279) = 279

GCD(3, 279) = ( 3 x 279 ) / 279

= 3 / 279

= 3

Step3:

LCM(3, 447) = 447

GCD(3, 447) = ( 3 x 447 ) / 447

= 3 / 447

= 3

So, Greatest Common Divisor of 975, 921, 279, 447 is 3
