Steps to Calculate GCD of 40, 34, 16, 68 using LCM Formula

Given numbers are 40, 34, 16, 68

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(40, 34) = 680

GCD(40, 34) = ( 40 x 34 ) / 680

= 40 / 34

= 40


Step2:

LCM(2, 16) = 16

GCD(2, 16) = ( 2 x 16 ) / 16

= 2 / 16

= 2


Step3:

LCM(2, 68) = 68

GCD(2, 68) = ( 2 x 68 ) / 68

= 2 / 68

= 2


So, Greatest Common Divisor of 40, 34, 16, 68 is 2
