Steps to Calculate GCD of 213, 771, 322, 691 using LCM Formula
Given numbers are 213, 771, 322, 691
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(213, 771) = 54741
GCD(213, 771) = ( 213 x 771 ) / 54741
= 213 / 771
= 213
Step2:
LCM(3, 322) = 966
GCD(3, 322) = ( 3 x 322 ) / 966
= 3 / 322
= 3
Step3:
LCM(1, 691) = 691
GCD(1, 691) = ( 1 x 691 ) / 691
= 1 / 691
= 1
So, Greatest Common Divisor of 213, 771, 322, 691 is 1
