Given numbers are 449, 681, 438, 457

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

Apply this formula for all numbers.

Step1:

LCM(449, 681) = 305769

GCD(449, 681) = ( 449 x 681 ) / 305769

= 449 / 681

= 449

Step2:

LCM(1, 438) = 438

GCD(1, 438) = ( 1 x 438 ) / 438

= 1 / 438

= 1

Step3:

LCM(1, 457) = 457

GCD(1, 457) = ( 1 x 457 ) / 457

= 1 / 457

= 1

So, Greatest Common Divisor of 449, 681, 438, 457 is 1
