Least common multiple (LCM) of 7, 21, 763 is 2289.
LCM(7, 21, 763) = 2289
LCM of 7, 21, 763
Least common multiple or lowest common denominator (lcd) can be calculated in three ways
- Least Common Multiple of 7, 21, 763 by common division method
- Least Common Multiple of 7, 21, 763 with GCF Formula
Least Common Multiple (LCM) of 7,21,763 is 2289
| 7 | 7, 21, 763 |
| 1, 3, 109 |
∴ So the LCM of the given numbers is 7 x 1 x 3 x 109 = 2289
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 7,21,763 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(7,21,763) = 7
common factors(in case of two or more numbers have common factors) = 7
GCF(7,21,763) x common factors =7 x 7 = 49
LCM(7,21,763) = ( 7 × 21 × 763 ) / 49
LCM(7,21,763) = 112161 / 49
LCM(7,21,763) = 2289
∴ Least Common Multiple of 7,21,763 is 2289
