Given numbers are 6870,5391

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 6870,5391 is 12345390.

Find LCM of 6870,5391 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

3 x 2290 x 1797 = 12345390

Therefore, the lowest common multiple of 6870,5391 is 12345390.

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

6870 x 5391 = 37036170

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

6870 : 1, 2, 3, 5, 6, 10, 15, 30, 229, 458, 687, 1145, 1374, 2290, 3435, 6870

5391 : 1, 3, 9, 599, 1797, 5391

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 6870,5391, is 3.

Now, the common factors can be found like this.

6870:2x 3x 5x 229

5391:3x 3x 599

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

= 1

Therefore, the value for common factors is 1.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 37036170/(3x1)

LCM = 37036170/3

LCM = 12345390

Thus, we can understand that the LCM of 6870,5391 is 12345390.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 3934, 8033
