Steps to Calculate GCD of 811, 172, 885, 123 using LCM Formula
Given numbers are 811, 172, 885, 123
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(811, 172) = 139492
GCD(811, 172) = ( 811 x 172 ) / 139492
= 811 / 172
= 811
Step2:
LCM(1, 885) = 885
GCD(1, 885) = ( 1 x 885 ) / 885
= 1 / 885
= 1
Step3:
LCM(1, 123) = 123
GCD(1, 123) = ( 1 x 123 ) / 123
= 1 / 123
= 1
So, Greatest Common Divisor of 811, 172, 885, 123 is 1
