Given numbers are 8481,2139

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

The LCM of 8481,2139 is 6046953.

Find LCM of 8481,2139 with Prime Factorization

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

3 x 2827 x 713 = 6046953

Therefore, the lowest common multiple of 8481,2139 is 6046953.

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.

8481 x 2139 = 18140859

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.

8481 : 1, 3, 11, 33, 257, 771, 2827, 8481

2139 : 1, 3, 23, 31, 69, 93, 713, 2139

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 8481,2139, is 3.

Now, the common factors can be found like this.

8481:3x 11x 257

2139:3x 23x 31

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 = 18140859/(3x1)

LCM = 18140859/3

LCM = 6046953

Thus, we can understand that the LCM of 8481,2139 is 6046953.

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

• LCM of 7815, 4055
• LCM of 9907, 5936
