Least common multiple (LCM) of 17, 42, 221 is 9282.
LCM(17, 42, 221) = 9282
LCM of 17, 42, 221
Least common multiple or lowest common denominator (lcd) can be calculated in three ways
- Least Common Multiple of 17, 42, 221 by common division method
- Least Common Multiple of 17, 42, 221 with GCF Formula
Least Common Multiple (LCM) of 17,42,221 is 9282
| 17 | 17, 42, 221 |
| 1, 42, 13 |
∴ So the LCM of the given numbers is 17 x 1 x 42 x 13 = 9282
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 17,42,221 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(17,42,221) = 1
common factors(in case of two or more numbers have common factors) = 17
GCF(17,42,221) x common factors =1 x 17 = 17
LCM(17,42,221) = ( 17 × 42 × 221 ) / 17
LCM(17,42,221) = 157794 / 17
LCM(17,42,221) = 9282
∴ Least Common Multiple of 17,42,221 is 9282
