Given numbers are 987, 327, 531, 449

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

Apply this formula for all numbers.

Step1:

LCM(987, 327) = 107583

GCD(987, 327) = ( 987 x 327 ) / 107583

= 987 / 327

= 987

Step2:

LCM(3, 531) = 531

GCD(3, 531) = ( 3 x 531 ) / 531

= 3 / 531

= 3

Step3:

LCM(3, 449) = 1347

GCD(3, 449) = ( 3 x 449 ) / 1347

= 3 / 449

= 3

So, Greatest Common Divisor of 987, 327, 531, 449 is 1
