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 least common multiple of 4 , 5 , 3 , 7 = 420
The smallest number that will can be divided by 2, 3, 4, 5, 6 and 7 is 420.

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 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, 4, 5, and 7 is 420.
The least common multiple (LCM) of a set of numbers is the smallest number that is a multiple of each number in the set. To find the LCM of 2, 3, 5, 7, and 11, we need to calculate the prime factorization of each number. The prime factorization of these numbers are 2 = 2, 3 = 3, 5 = 5, 7 = 7, and 11 = 11. To find the LCM, we multiply the highest power of each prime factor that appears in the factorizations, which results in LCM = 2 * 3 * 5 * 7 * 11 = 2310. Therefore, the least common multiple of 2, 3, 5, 7, and 11 is 2310.
The number 1 would be the smallest multiple of 7. 7 times 1 = 7
The smallest multiple of 7 is 7.
