To find the LCM of three numbers, you would start by splitting them into their prime factors. In this case, the three numbers already are prime. The next step would be to eradicate any duplicate factors. In this case, there are none. Thus, all we have to do is multiply the primes, 3, 5 and 7 together. This gives us:
3x5x7 = 105
So the LCM of 3 5 and 7 is 105
7 its self is the smallest multiple of 7 and is also 2 x 3.5.
The lowest common multiple of 5 and 7 is 35.
The smallest three digit multiple of 15 is 105, which is 15 x 7.
The least common multiple of 4 , 5 , 3 , 7 = 420
The least common multiple of 2 , 3 , 5 , 7 = 210
105
7 its self is the smallest multiple of 7 and is also 2 x 3.5.
The lowest common multiple of 5 and 7 is 35.
The smallest three digit multiple of 15 is 105, which is 15 x 7.
35

LCM = 35

The least common multiple (LCM) is often also called the lowest common multiple or smallest common multiple. Keep in mind that these different terms all refer to the same thing: the smallest positive integer which is a multiple of two or more numbers.The least common multiple of 2, 3, 5, 7, and 11 is 2,310.2310

The number 1 would be the smallest multiple of 7. 7 times 1 = 7
