Steps to Calculate GCD of 211, 145, 891, 163 using LCM Formula
Given numbers are 211, 145, 891, 163
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(211, 145) = 30595
GCD(211, 145) = ( 211 x 145 ) / 30595
= 211 / 145
= 211
Step2:
LCM(1, 891) = 891
GCD(1, 891) = ( 1 x 891 ) / 891
= 1 / 891
= 1
Step3:
LCM(1, 163) = 163
GCD(1, 163) = ( 1 x 163 ) / 163
= 1 / 163
= 1
So, Greatest Common Divisor of 211, 145, 891, 163 is 1
