Steps to Calculate GCD of 840, 214, 345, 743 using LCM Formula

Given numbers are 840, 214, 345, 743

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

Apply this formula for all numbers.

Step1:

LCM(840, 214) = 89880

GCD(840, 214) = ( 840 x 214 ) / 89880

= 840 / 214

= 840


Step2:

LCM(2, 345) = 690

GCD(2, 345) = ( 2 x 345 ) / 690

= 2 / 345

= 2


Step3:

LCM(1, 743) = 743

GCD(1, 743) = ( 1 x 743 ) / 743

= 1 / 743

= 1


So, Greatest Common Divisor of 840, 214, 345, 743 is 1
