The way to solve this is as follows:
least common multiple of 15 and 82
The Least Common Multiple of 5, 15, and 3 is 15.
15, 30, 45
15 & 20 have an infinite number of Common Multiples; the first three are 60, 120 and 180.
60 is the lowest common multiple of 20 and 15.
15
15
Fifteen is the least common multiple of three and five. 3 * 5 = 15 5 * 3 = 15
15
60
60
Since 3 is a factor of 15, the first three common multiples of 3 and 15 are 15, 30, and 45.
The Least Common Multiple (LCM) of (15,3) is 15
The LCM or least common multiple of 3 and 5 is 15.The GCF or greatest common factor of 3 and 5 is 1.
The Greatest Common Factor of 15, 45: 15The Least Common Multiple of 15, 45: 45
15 is a multiple of 3. 15 is a multiple of 5. That makes it a common multiple of 3 and 5.
The LCM of 35 and 105 is 105. Since 105 is a multiple of 35, it is automatically the LCM.
