Steps to Calculate GCD of 861, 129, 811, 214 using LCM Formula
Given numbers are 861, 129, 811, 214
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(861, 129) = 37023
GCD(861, 129) = ( 861 x 129 ) / 37023
= 861 / 129
= 861
Step2:
LCM(3, 811) = 2433
GCD(3, 811) = ( 3 x 811 ) / 2433
= 3 / 811
= 3
Step3:
LCM(1, 214) = 214
GCD(1, 214) = ( 1 x 214 ) / 214
= 1 / 214
= 1
So, Greatest Common Divisor of 861, 129, 811, 214 is 1
