Given numbers are 499,400,638

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

The LCM of 499,400,638 is 63672400.

Find LCM of 499,400,638 with Prime Factorization

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

2 x 499 x 200 x 319 = 63672400

Therefore, the lowest common multiple of 499,400,638 is 63672400.

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.

499 x 400 x 638 = 127344800

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.

499 : 1, 499

400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400

638 : 1, 2, 11, 22, 29, 58, 319, 638

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 499,400,638, is 1.

Now, the common factors can be found like this.

499:499

400:2x 2x 2x 2x 5x 5

638:2x 11x 29

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 = 127344800/(1x2)

LCM = 127344800/2

LCM = 63672400

Thus, we can understand that the LCM of 499,400,638 is 63672400.

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

• LCM of 238, 685, 165
