The meaning of least common factor (LCM) is to find the smallest number that divides any two integers evenly. LCM is used mainly in fractions to find a common number for both the integers. We use LCM for solving problems, lining up cycles or even synchronizing of events, also to schedule tasks in everyday life.

What is the LCM of 14 and 15?

We use LCM of 14 and 15 to find the smallest number that divides both the numbers equally. The smallest positive number is the number that divides both numbers equally, is 210 without leaving any remainder. LCM is used mainly in fractions to find a common number for both the integers.

How to find the LCM of 14 and 15?

The LCM of 14 and 15 can be found by the following methods like division method, listing multiples, prime factorization.

LCM of 14 and 15 using Division method:

In division method, we divide both the numbers, we begin with dividing side by side the smallest number. We continue dividing until we get a common number that divides both the numbers equally. It makes it easier for the children to focus on prime factors and identify them.

2 divides 14 and not 15

3 divides 15 and not 14

5 divides 15 and not 14

7 divides only 14.

Now multiply the divisors : 2×3×5×7=210 which is the LCM.

LCM of 14 and 15 using Listing multiples:

Start by listing multiples of both the numbers separately:

Multiples of 14 are 14,28,42,56,70,84,98,112,126,140…..

Multiples of 15 are 15,30,45,60,75,90,105,120,135,150…..

The least common factor from the list is 210. Therefore, the LCM of 14 and 15 is 210.

LCM of 14 and 15 using Prime factorization:

We part both the numbers unto factors:

Factor of 14: 2×7

Factors of 15: 3×5

Take the powers of both the numbers and multiply together:

LCM=2x3x5x7=210.
