Given numbers are 643,643,630,625

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

The LCM of 643,643,630,625 is 50636250.

Find LCM of 643,643,630,625 with Prime Factorization

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

5 x 643 x 1 x 1 x 126 x 125 = 50636250

Therefore, the lowest common multiple of 643,643,630,625 is 50636250.

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.

643 x 643 x 630 x 625 = 162795543750

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.

643 : 1, 643

643 : 1, 643

630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630

625 : 1, 5, 25, 125, 625

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 643,643,630,625, is 1.

Now, the common factors can be found like this.

643:643

643:643

630:2x 3x 3x 5x 7

625:5x 5x 5x 5

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

5x 643 = 3215

Therefore, the value for common factors is 3215.

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 = 162795543750/(1x3215)

LCM = 162795543750/3215

LCM = 50636250

Thus, we can understand that the LCM of 643,643,630,625 is 50636250.

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