Steps to Calculate GCD of 34, 74, 18, 68 using LCM Formula
Given numbers are 34, 74, 18, 68
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(34, 74) = 1258
GCD(34, 74) = ( 34 x 74 ) / 1258
= 34 / 74
= 34
Step2:

GCD(2, 18) = ( 2 x 18 ) / 18
= 2 / 18
= 2
Step3:
LCM(2, 68) = 68
GCD(2, 68) = ( 2 x 68 ) / 68
= 2 / 68
= 2
So, Greatest Common Divisor of 34, 74, 18, 68 is 2
