What are the common multiples of 14 and 28?
To find the common multiples, we first need to break the numbers down into their prime factors: 14 = 2x7 28 = 2x2x7 The next step is to identify any common factors. In this case, both numbers have a single 2 and a single 7, so we can discard one of each. This leaves us with 2, 2 and 7. Multiply these together for the LCM: 2x2x7 = 28 To find other multiples, you now simply multiply this number by any integer. For instance, 28x2, 28x3, 28x4.... Thus the first few common multiples of 14 and 28 are 28, 56, 84, 112.
What is the lcm of 2 and 16?
The answer is 16. LCM you try to find the lowest possible common multiple and so the answer is 16. Why? Ex. Multiples of 2 | of 16 2 {16} 4 6 8 10 12 14 {16}
