How to calculate the least common multiple of 8 and 24?
The formula of LCM is LCM (a,b) = ( a × b) / GCF (a,b). We need to calculate greatest common factor 8 and 24, than apply into the LCM equation. Least common multiple can be found by multiplying the highest exponent prime factors of 8 and 24. First we will calculate the prime factors of 8 and 24. Prime factors of 8 are 2.
Which is the least common multiple of 8, 12 and 18?
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. Use Shwetyank’s method in the class and an exam. The marking schema will be set up for that approach. My alternative approach – helps with understanding. Target: LCM of 8,12 and 18.
