Given numbers are 816,113,687

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

The LCM of 816,113,687 is 21115632.

Find LCM of 816,113,687 with Prime Factorization

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

3 x 272 x 113 x 229 = 21115632

Therefore, the lowest common multiple of 816,113,687 is 21115632.

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.

816 x 113 x 687 = 63346896

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.

816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816

113 : 1, 113

687 : 1, 3, 229, 687

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 816,113,687, is 1.

Now, the common factors can be found like this.

816:2x 2x 2x 2x 3x 17

113:113

687:3x 229

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

3 = 3

Therefore, the value for common factors is 3.

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 = 63346896/(1x3)

LCM = 63346896/3

LCM = 21115632

Thus, we can understand that the LCM of 816,113,687 is 21115632.

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