Steps to Calculate GCD of 679, 212, 386, 643 using LCM Formula
Given numbers are 679, 212, 386, 643
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(679, 212) = 143948
GCD(679, 212) = ( 679 x 212 ) / 143948
= 679 / 212
= 679
Step2:
LCM(1, 386) = 386
GCD(1, 386) = ( 1 x 386 ) / 386
= 1 / 386
= 1
Step3:
LCM(1, 643) = 643
GCD(1, 643) = ( 1 x 643 ) / 643
= 1 / 643
= 1
So, Greatest Common Divisor of 679, 212, 386, 643 is 1
