Given numbers are 667,814,816

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

The LCM of 667,814,816 is 221518704.

Find LCM of 667,814,816 with Prime Factorization

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

2 x 667 x 407 x 408 = 221518704

Therefore, the lowest common multiple of 667,814,816 is 221518704.

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.

667 x 814 x 816 = 443037408

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.

667 : 1, 23, 29, 667

814 : 1, 2, 11, 22, 37, 74, 407, 814

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 667,814,816, is 1.

Now, the common factors can be found like this.

667:23x 29

814:2x 11x 37

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

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

2 = 2

Therefore, the value for common factors is 2.

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 = 443037408/(1x2)

LCM = 443037408/2

LCM = 221518704

Thus, we can understand that the LCM of 667,814,816 is 221518704.

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

• LCM of 521, 774, 325
