Steps to Calculate GCD of 66, 34, 42, 66 using LCM Formula

Given numbers are 66, 34, 42, 66

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

Apply this formula for all numbers.

Step1:

LCM(66, 34) = 1122

GCD(66, 34) = ( 66 x 34 ) / 1122

= 66 / 34

= 66


Step2:

LCM(2, 42) = 42

GCD(2, 42) = ( 2 x 42 ) / 42

= 2 / 42

= 2


Step3:

LCM(2, 66) = 66

GCD(2, 66) = ( 2 x 66 ) / 66

= 2 / 66

= 2


So, Greatest Common Divisor of 66, 34, 42, 66 is 2
