Steps to Calculate GCD of 811, 646, 153, 220 using LCM Formula
Given numbers are 811, 646, 153, 220
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(811, 646) = 523906
GCD(811, 646) = ( 811 x 646 ) / 523906
= 811 / 646
= 811
Step2:
LCM(1, 153) = 153
GCD(1, 153) = ( 1 x 153 ) / 153
= 1 / 153
= 1
Step3:
LCM(1, 220) = 220
GCD(1, 220) = ( 1 x 220 ) / 220
= 1 / 220
= 1
So, Greatest Common Divisor of 811, 646, 153, 220 is 1
