Given numbers are 449, 969, 621, 306

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

Apply this formula for all numbers.

Step1:

LCM(449, 969) = 435081

GCD(449, 969) = ( 449 x 969 ) / 435081

= 449 / 969

= 449

Step2:

LCM(1, 621) = 621

GCD(1, 621) = ( 1 x 621 ) / 621

= 1 / 621

= 1

Step3:

LCM(1, 306) = 306

GCD(1, 306) = ( 1 x 306 ) / 306

= 1 / 306

= 1

So, Greatest Common Divisor of 449, 969, 621, 306 is 1
