How do you find the least common multiple of 30 and 3?

Answer 1

Least Common Multiple of #30# and #3# is #30#.

If you have two numbers, smaller one among which is a factor of lager one, then GCF (Greatet Common Factor) of the two is smaller number and larger number is LCM (Least Common Multiple).

Here, among two numbers #3# and #30#, as #3# is a factor of #30#,

Least Common Multiple of #30# and #3# is #30#.

To find the least common multiple (LCM) of 30 and 3, you can use the prime factorization method.

Prime factorize both numbers:
- 30 = 2 * 3 * 5
- 3 = 3
Identify the highest power of each prime factor:
- For 2, it appears once in 30.
- For 3, it appears once in 30 and once in 3.
- For 5, it appears once in 30.
Multiply the highest powers of all prime factors: LCM = 2^1 * 3^1 * 5^1 = 2 * 3 * 5 = 30

Therefore, the least common multiple of 30 and 3 is 30.

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.
