How to get the least common multiple of 8 and 2?
To get the Least Common Multiple (LCM) of 8 and 2 we need to factor each value first and then we choose all the factors which appear in any column and multiply them: The Least Common Multiple (LCM) is: 2 x 2 x 2 = 8 You can always share this solution
Which is the least common multiple of 18?
Multiples of 18 are {18,36,54,72,90,108,126,144……} Hence common multiples are {72,144,…….} Another shorter way is to write numbers as multiplication of its prime factors 12 = 2×2×3 → 2 comes twice and 3 once. So maximum times is three times for 2 and two times for 3. Hence, Least Common Multiple is 2×2×2×3×3 = 72.
How to calculate the least common multiple ( LCM )?
Least common multiple or lowest common denominator (lcd) can be calculated in two way; with the LCM formula calculation of greatest common factor (GCF), or multiplying the prime factors with the highest exponent factor. The formula of LCM is LCM (a,b) = ( a × b) / GCF (a,b).
