Which is the smallest 5 multiple of 7?

Answer. 10003 is the smallest 5-digit multiple of 7.

#### How do you solve for LCM?

One way to find the least common multiple of two numbers is to first list the prime factors of each number. Then multiply each factor the greatest number of times it occurs in either number. If the same factor occurs more than once in both numbers, you multiply the factor the greatest number of times it occurs.

#### How do you find prime factorization easily?

Step 1: Divide the given number by the smallest prime number. In this case, the smallest prime number should divide the number exactly. Step 2: Again, divide the quotient by the smallest prime number. Step 3: Repeat the process, until the quotient becomes 1.
