Steps to Calculate GCD of 840, 672, 349, 768 using LCM Formula

Given numbers are 840, 672, 349, 768

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

Apply this formula for all numbers.

Step1:

LCM(840, 672) = 3360

GCD(840, 672) = ( 840 x 672 ) / 3360

= 840 / 672

= 840


Step2:

LCM(168, 349) = 58632

GCD(168, 349) = ( 168 x 349 ) / 58632

= 168 / 349

= 168


Step3:

LCM(1, 768) = 768

GCD(1, 768) = ( 1 x 768 ) / 768

= 1 / 768

= 1


So, Greatest Common Divisor of 840, 672, 349, 768 is 1
