What is the LCM of 30 and 35?

Misha Larkins [42]

Answer: 210

Explanation: To find the least common multiple for the integers 30 and 35, we start by making a factor tree for each of our integers.

So 30 is 10 · 3 and 10 is 5 · 2.

35 is 7 · 5.

Notice that our 5's match up as factors of each of our integers.

When finding the least common multiple, we simply multiply all of our factors together but since the 5's match up,

we only multiply by a 5 once.

So our least common multiple or LCM is

5 · the 2 that doesn't match up · the 3 that

doesn't match up · the 7 that doesn't match up.

So we have 5 · 2 · 3 · 7 or 210.

Work is shown below.
