Given numbers are 8618,7870

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

The LCM of 8618,7870 is 33911830.

Find LCM of 8618,7870 with Prime Factorization

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

2 x 4309 x 3935 = 33911830

Therefore, the lowest common multiple of 8618,7870 is 33911830.

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.

8618 x 7870 = 67823660

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.

8618 : 1, 2, 31, 62, 139, 278, 4309, 8618

7870 : 1, 2, 5, 10, 787, 1574, 3935, 7870

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 8618,7870, is 2.

Now, the common factors can be found like this.

8618:2x 31x 139

7870:2x 5x 787

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 = 67823660/(2x1)

LCM = 67823660/2

LCM = 33911830

Thus, we can understand that the LCM of 8618,7870 is 33911830.

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

• LCM of 7632, 1415
• LCM of 8565, 7512
