Steps to Calculate GCD of 686, 643, 667, 434 using LCM Formula
Given numbers are 686, 643, 667, 434
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(686, 643) = 441098
GCD(686, 643) = ( 686 x 643 ) / 441098
= 686 / 643
= 686
Step2:
LCM(1, 667) = 667
GCD(1, 667) = ( 1 x 667 ) / 667
= 1 / 667
= 1
Step3:
LCM(1, 434) = 434
GCD(1, 434) = ( 1 x 434 ) / 434
= 1 / 434
= 1
So, Greatest Common Divisor of 686, 643, 667, 434 is 1
