Given numbers are 643,286,212,501

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

The LCM of 643,286,212,501 is 9766087188.

Find LCM of 643,286,212,501 with Prime Factorization

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

2 x 643 x 143 x 106 x 501 = 9766087188

Therefore, the lowest common multiple of 643,286,212,501 is 9766087188.

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 286 x 212 x 501 = 19532174376

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

286 : 1, 2, 11, 13, 22, 26, 143, 286

212 : 1, 2, 4, 53, 106, 212

501 : 1, 3, 167, 501

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 643,286,212,501, is 1.

Now, the common factors can be found like this.

643:643

286:2x 11x 13

212:2x 2x 53

501:3x 167

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 = 19532174376/(1x2)

LCM = 19532174376/2

LCM = 9766087188

Thus, we can understand that the LCM of 643,286,212,501 is 9766087188.
