Steps to Calculate GCD of 645, 826, 723, 449 using LCM Formula

Given numbers are 645, 826, 723, 449

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

Apply this formula for all numbers.

Step1:

LCM(645, 826) = 532770

GCD(645, 826) = ( 645 x 826 ) / 532770

= 645 / 826

= 645


Step2:

LCM(1, 723) = 723

GCD(1, 723) = ( 1 x 723 ) / 723

= 1 / 723

= 1


Step3:

LCM(1, 449) = 449

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

= 1 / 449

= 1
