The factors of 15 are: 1, 3, 5, 15 The factors of 18 are: 1, 2, 3, 6, 9, 18
The first step is to break the numbers down into their prime factors: 18 = 2x3x3 5 = 5 The next step would be to identify any common factors. In this case, there are none. Thus we simply multiply all the factors together: 2x3x3x5 = 90 And so the LCM of 18 and 5 is 90.

Prime factors of 18 are 2 and 3 Prime factors of 45 are 3 and 5
The factors of 18 are: 1, 2, 3, 6, 9, and 18.The prime factors of 18 are: 2 and 3.The factors of 20 are: 1, 2, 4, 5, 10, and 20.The prime factors of 20 are: 2 and 5.
The only common factor of 5, 9, and 18 is 1. The factors of 5 are 1 and 5 The factors of 9 are 1, 3, and 9 The factors of 18 are 1, 2, 3, 6, 9 and 18 The common factor is 1.
1, 2, 3, 6, 9, 18 are the first and only 6 factors of 18
The factors of 18 are 1,2,3,6,9 and 18. For them to be common, they need to be compared to another set of factors.
Including 1 and 18, 18 has 6 factors: 1, 2, 3, 6, 9, and 18.

The factors of 15 are: 1, 3, 5, 15 The factors of 18 are: 1, 2, 3, 6, 9, 18
Prime factors of 18 are 2 and 3 Prime factors of 15 are 3 and 5
The prime factors of 18 are 2, 3 and 3 The prime factors of 25 are 5 and 5 There are no factors (other than 1) common to both 18 and 25.
The first step is to break the numbers down into their prime factors: 18 = 2x3x3 5 = 5 The next step would be to identify any common factors. In this case, there are none. Thus we simply multiply all the factors together: 2x3x3x5 = 90 And so the LCM of 18 and 5 is 90.
First list the factors of each. For 18, that's 1, 2, 3, 6, 9, and 18. For 20, that's 1, 2, 4, 5, 10, and 20. From these, you could add all of the factors of 18 to get 39. Or you could add 20, 10, and 9. Or 20, 10, 5, and 4. Or . . . you get the idea.
The factors of 18 are: 1, 2, 3, 6, 9, and 18.The prime factors of 18 are: 2 and 3.The factors of 39 are: 1, 3, 13, and 39.The prime factors of 39 are: 3 and 13.The factors of 45 are: 1, 3, 5, 9, 15, and 45.The prime factors of 45 are: 3 and 5.
