Steps to Calculate GCD of 123, 820, 293, 956 using LCM Formula
Given numbers are 123, 820, 293, 956
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(123, 820) = 2460
GCD(123, 820) = ( 123 x 820 ) / 2460
= 123 / 820
= 123
Step2:
LCM(41, 293) = 12013
GCD(41, 293) = ( 41 x 293 ) / 12013
= 41 / 293
= 41
Step3:
LCM(1, 956) = 956
GCD(1, 956) = ( 1 x 956 ) / 956
= 1 / 956
= 1
So, Greatest Common Divisor of 123, 820, 293, 956 is 1
