Given numbers are 643,643,508

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

The LCM of 643,643,508 is 326644.

Find LCM of 643,643,508 with Prime Factorization

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

643 x 1 x 1 x 508 = 326644

Therefore, the lowest common multiple of 643,643,508 is 326644.

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 508 = 210032092

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

508 : 1, 2, 4, 127, 254, 508

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 643,643,508, is 1.

Now, the common factors can be found like this.

643:643

643:643

508:2x 2x 127

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

643 = 643

Therefore, the value for common factors is 643.

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 = 210032092/(1x643)

LCM = 210032092/643

LCM = 326644

Thus, we can understand that the LCM of 643,643,508 is 326644.

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

• LCM of 640, 348, 509
