Given numbers are 8390,3105

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

The LCM of 8390,3105 is 5210190.

Find LCM of 8390,3105 with Prime Factorization

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

5 x 1678 x 621 = 5210190

Therefore, the lowest common multiple of 8390,3105 is 5210190.

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.

8390 x 3105 = 26050950

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.

8390 : 1, 2, 5, 10, 839, 1678, 4195, 8390

3105 : 1, 3, 5, 9, 15, 23, 27, 45, 69, 115, 135, 207, 345, 621, 1035, 3105

5 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 8390,3105, is 5.

Now, the common factors can be found like this.

8390:2x 5x 839

3105:3x 3x 3x 5x 23

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 = 26050950/(5x1)

LCM = 26050950/5

LCM = 5210190

Thus, we can understand that the LCM of 8390,3105 is 5210190.

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

• LCM of 4940, 9081
