Given numbers are 449, 343, 418, 664

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

Apply this formula for all numbers.

Step1:

LCM(449, 343) = 154007

GCD(449, 343) = ( 449 x 343 ) / 154007

= 449 / 343

= 449

Step2:

LCM(1, 418) = 418

GCD(1, 418) = ( 1 x 418 ) / 418

= 1 / 418

= 1

Step3:

LCM(1, 664) = 664

GCD(1, 664) = ( 1 x 664 ) / 664

= 1 / 664

= 1

So, Greatest Common Divisor of 449, 343, 418, 664 is 1
