LCM for 16, 36 and 48
What's the Least Common Multiple (LCM) of 16, 36 and 48?
Answer
(One hundred forty-four)
144 is the smallest positive integer that 16, 36 and 48 all divide without a remainder — every other common multiple of the three is a multiple of it.
Finding the LCM of 16, 36 and 48 by Prime Factorization
Split all three numbers into prime factors, then take every prime that shows up in at least one of them, each raised to the highest power it reaches there. Multiplying those highest powers gives the least common multiple:
All Prime Factors of 16: 2 × 2 × 2 × 2 (exponent form: 24)
All Prime Factors of 36: 2 × 2 × 3 × 3 (exponent form: 22 × 32)
All Prime Factors of 48: 2 × 2 × 2 × 2 × 3 (exponent form: 24 × 3)
| Prime factor | 16 | 36 | 48 | Highest power |
|---|---|---|---|---|
| 2 | 24 | 22 | 24 | 24 |
| 3 | — | 32 | 3 | 32 |
LCM = 24 × 32 = 144
Checking the LCM of 16, 36 and 48 Two Numbers at a Time
The least common multiple is associative, so three numbers can be handled as two pairs: first the LCM of the first two, then the LCM of that value and the third. Each pair goes through the two-number formula, which uses the greatest common divisor:
LCM(a, b) = (a × b) ÷ GCD(a, b)
LCM(16, 36) = (16 × 36) ÷ 4 = 576 ÷ 4 = 144
LCM(144, 48) = (144 × 48) ÷ 48 = 6,912 ÷ 48 = 144
LCM(16, 36, 48) = 144
The pairs may be taken in any order — 36 and 48 first, then 16 — and the answer is the same 144. That is exactly why the two routes on this page agree.
