Steps to Calculate GCD of 686, 604, 421, 845 using LCM Formula

Given numbers are 686, 604, 421, 845

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

Apply this formula for all numbers.

Step1:

LCM(686, 604) = 207172

GCD(686, 604) = ( 686 x 604 ) / 207172

= 686 / 604

= 686


Step2:

LCM(2, 421) = 842

GCD(2, 421) = ( 2 x 421 ) / 842

= 2 / 421

= 2


Step3:

LCM(1, 845) = 845

GCD(1, 845) = ( 1 x 845 ) / 845

= 1 / 845

= 1


So, Greatest Common Divisor of 686, 604, 421, 845 is 1
