Least common multiple (LCM) of 42, 89, 111 is 138306.
LCM(42, 89, 111) = 138306
LCM of 42, 89, 111
Least common multiple or lowest common denominator (lcd) can be calculated in three ways
- Least Common Multiple of 42, 89, 111 by common division method
- Least Common Multiple of 42, 89, 111 with GCF Formula
Least Common Multiple (LCM) of 42,89,111 is 138306
| 3 | 42, 89, 111 |
| 14, 89, 37 |
∴ So the LCM of the given numbers is 3 x 14 x 89 x 37 = 138306
The formula of LCM is LCM(a1,a2,a3....,an) = ( a1 × a2 × a3 × .... × an) / GCF(a1,a2,a3....,an) x common factors(if more than 2 numbers have common factors).
We need to calculate greatest common factor of 42,89,111 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(42,89,111) = 1
common factors(in case of two or more numbers have common factors) = 3
GCF(42,89,111) x common factors =1 x 3 = 3
LCM(42,89,111) = ( 42 × 89 × 111 ) / 3
LCM(42,89,111) = 414918 / 3
LCM(42,89,111) = 138306
∴ Least Common Multiple of 42,89,111 is 138306
