LCM is a common multiple, the smallest value between the numbers 3 and 8. Did you know? We apply LCM unknowingly in everyday situations like setting alarms and to synchronize traffic lights and when making music.
The LCM of 3 and 8 is 24. We can find the LCM using the Listing multiples method, the prime factorization method and the long division method. These are explained below.
Write down the multiples of the numbers. Don’t stop too early.
Multiples of 3 = 3,6,9,12,18,21,24…
Multiples of 8 = 8, 16,24,…
Find the smallest number common between the written multiples of 3 and 8
The smallest common multiple is 24.
Thus, LCM(3, 8) = 24.
factorize the numbers into its prime factors
3 = 3×1
8 = 2×2×2
find the highest powers of the factors of 3 and 8
Multiply the highest powers
LCM(3,8) = 24
Write the numbers 3,8 in a row
Divide them by their common prime factors, if there is one
Carry forward the numbers that are left undivided by the previously chosen factor
Continue dividing until the remainder is ‘1’
Multiply the divisors to find the LCM
LCM(3, 8) = 24.
Use LCM(a,b) = a×b/HCF(a,b) to find the LCM of 3 and 8.
Goods are received by a shipping company every 3 and 8 months. If the shipments have been received today, when will they next arrive at the same day?
LCM of (3,x) is 6. Find x.
