Given numbers are 643,559,559,287

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

The LCM of 643,559,559,287 is 103158419.

Find LCM of 643,559,559,287 with Prime Factorization

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

13 x 43 x 643 x 1 x 1 x 287 = 103158419

Therefore, the lowest common multiple of 643,559,559,287 is 103158419.

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 559 x 559 x 287 = 57665556221

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

559 : 1, 13, 43, 559

559 : 1, 13, 43, 559

287 : 1, 7, 41, 287

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 643,559,559,287, is 1.

Now, the common factors can be found like this.

643:643

559:13x 43

559:13x 43

287:7x 41

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

13x 43 = 559

Therefore, the value for common factors is 559.

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 = 57665556221/(1x559)

LCM = 57665556221/559

LCM = 103158419

Thus, we can understand that the LCM of 643,559,559,287 is 103158419.
