LCM(49, 42, 85) = 24990
LCM of 49, 42, 85
Least common multiple or lowest common denominator (lcd) can be calculated in three ways
- Least Common Multiple of 49, 42, 85 by common division method
- Least Common Multiple of 49, 42, 85 with GCF Formula
Least Common Multiple (LCM) of 49,42,85 is 24990
| 7 | 49, 42, 85 |
| 7, 6, 85 |
∴ So the LCM of the given numbers is 7 x 7 x 6 x 85 = 24990
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 49,42,85 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(49,42,85) = 1
common factors(in case of two or more numbers have common factors) = 7
GCF(49,42,85) x common factors =1 x 7 = 7
LCM(49,42,85) = ( 49 × 42 × 85 ) / 7
LCM(49,42,85) = 174930 / 7
LCM(49,42,85) = 24990
∴ Least Common Multiple of 49,42,85 is 24990
