Use the LCM of two or more numbers Calculator to find the Least Common Multiple of numbers 421, 842 i.e. 842 smallest integer divisible by all numbers.
Least common multiple (LCM) of 421, 842 is 842.
LCM(421, 842) = 842
Least common multiple or lowest common denominator (lcd) can be calculated in three ways
421 | 421, 842 |
1, 2 |
∴ So the LCM of the given numbers is 421 x 1 x 2 = 842
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 421,842 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(421,842) = 421
common factors(in case of two or more numbers have common factors) = 1
GCF(421,842) x common factors =421 x 1 = 421
LCM(421,842) = ( 421 × 842 ) / 421
LCM(421,842) = 354482 / 421
LCM(421,842) = 842
∴ Least Common Multiple of 421,842 is 842
