Steps to Calculate GCD of 18, 66, 30, 82 using LCM Formula
Given numbers are 18, 66, 30, 82
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(18, 66) = 198
GCD(18, 66) = ( 18 x 66 ) / 198
= 18 / 66
= 18
Step2:
LCM(6, 30) = 30
GCD(6, 30) = ( 6 x 30 ) / 30
= 6 / 30
= 6
Step3:
LCM(6, 82) = 246
GCD(6, 82) = ( 6 x 82 ) / 246
= 6 / 82
= 6
So, Greatest Common Divisor of 18, 66, 30, 82 is 2
