Steps to Calculate GCD of 445, 710, 164, 123 using LCM Formula
Given numbers are 445, 710, 164, 123
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(445, 710) = 63190
GCD(445, 710) = ( 445 x 710 ) / 63190
= 445 / 710
= 445
Step2:
LCM(5, 164) = 820
GCD(5, 164) = ( 5 x 164 ) / 820
= 5 / 164
= 5
Step3:
LCM(1, 123) = 123
GCD(1, 123) = ( 1 x 123 ) / 123
= 1 / 123
= 1
So, Greatest Common Divisor of 445, 710, 164, 123 is 1
