Given numbers are 449, 197, 39, 628

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

Apply this formula for all numbers.

Step1:

LCM(449, 197) = 88453

GCD(449, 197) = ( 449 x 197 ) / 88453

= 449 / 197

= 449

Step2:

LCM(1, 39) = 39

GCD(1, 39) = ( 1 x 39 ) / 39

= 1 / 39

= 1

Step3:

LCM(1, 628) = 628

GCD(1, 628) = ( 1 x 628 ) / 628

= 1 / 628

= 1

So, Greatest Common Divisor of 449, 197, 39, 628 is 1
