Given numbers are 638,513,962

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

The LCM of 638,513,962 is 157428414.

Find LCM of 638,513,962 with Prime Factorization

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

2 x 319 x 513 x 481 = 157428414

Therefore, the lowest common multiple of 638,513,962 is 157428414.

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 513 x 962 = 314856828

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

513 : 1, 3, 9, 19, 27, 57, 171, 513

962 : 1, 2, 13, 26, 37, 74, 481, 962

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,513,962, is 1.

Now, the common factors can be found like this.

638:2x 11x 29

513:3x 3x 3x 19

962:2x 13x 37

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 = 314856828/(1x2)

LCM = 314856828/2

LCM = 157428414

Thus, we can understand that the LCM of 638,513,962 is 157428414.

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