Steps to Calculate GCD of 639, 511, 840, 449 using LCM Formula

Given numbers are 639, 511, 840, 449

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

Apply this formula for all numbers.

Step1:

LCM(639, 511) = 326529

GCD(639, 511) = ( 639 x 511 ) / 326529

= 639 / 511

= 639


Step2:

LCM(1, 840) = 840

GCD(1, 840) = ( 1 x 840 ) / 840

= 1 / 840

= 1


Step3:

LCM(1, 449) = 449

GCD(1, 449) = ( 1 x 449 ) / 449

= 1 / 449

= 1


So, Greatest Common Divisor of 639, 511, 840, 449 is 1
