How do you find the least common multiple of 10 and 4?

Answer 1

Gianna Caruso

Any value multiplied by 10 will have 0 as the last digit.

So we need the least multiple of 4 that gives the last digit of 0, and that is #5xx4 = 20#

To find the least common multiple (LCM) of 10 and 4, you can use the prime factorization method.

First, find the prime factorization of each number:

Prime factorization of 10: 10 = 2 × 5
Prime factorization of 4: 4 = 2 × 2

Then, identify the highest power of each prime factor that appears in either factorization:

The highest power of 2 is 2^1
The highest power of 5 is 5^1

Finally, multiply these highest powers together to find the LCM: LCM = 2^1 × 5^1 = 2 × 5 = 10

So, the least common multiple of 10 and 4 is 10.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
