Given numbers are 638,299,656

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

The LCM of 638,299,656 is 62569936.

Find LCM of 638,299,656 with Prime Factorization

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

2 x 319 x 299 x 328 = 62569936

Therefore, the lowest common multiple of 638,299,656 is 62569936.

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.

638 x 299 x 656 = 125139872

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.

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

299 : 1, 13, 23, 299

656 : 1, 2, 4, 8, 16, 41, 82, 164, 328, 656

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,299,656, is 1.

Now, the common factors can be found like this.

638:2x 11x 29

299:13x 23

656:2x 2x 2x 2x 41

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 = 125139872/(1x2)

LCM = 125139872/2

LCM = 62569936

Thus, we can understand that the LCM of 638,299,656 is 62569936.

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

• LCM of 240, 409, 904
