Given numbers are 453,891,643,643

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

The LCM of 453,891,643,643 is 86509863.

Find LCM of 453,891,643,643 with Prime Factorization

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

3 x 643 x 151 x 297 x 1 x 1 = 86509863

Therefore, the lowest common multiple of 453,891,643,643 is 86509863.

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.

453 x 891 x 643 x 643 = 166877525727

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.

453 : 1, 3, 151, 453

891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891

643 : 1, 643

643 : 1, 643

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 453,891,643,643, is 1.

Now, the common factors can be found like this.

453:3x 151

891:3x 3x 3x 3x 11

643:643

643:643

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

3x 643 = 1929

Therefore, the value for common factors is 1929.

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 = 166877525727/(1x1929)

LCM = 166877525727/1929

LCM = 86509863

Thus, we can understand that the LCM of 453,891,643,643 is 86509863.
