Steps to Calculate GCD of 669, 135, 12, 439 using LCM Formula
Given numbers are 669, 135, 12, 439
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(669, 135) = 30105
GCD(669, 135) = ( 669 x 135 ) / 30105
= 669 / 135
= 669
Step2:
LCM(3, 12) = 12
GCD(3, 12) = ( 3 x 12 ) / 12
= 3 / 12
= 3
Step3:
LCM(3, 439) = 1317
GCD(3, 439) = ( 3 x 439 ) / 1317
= 3 / 439
= 3
So, Greatest Common Divisor of 669, 135, 12, 439 is 1
