Given numbers are 513,955,643,643

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

The LCM of 513,955,643,643 is 315015345.

Find LCM of 513,955,643,643 with Prime Factorization

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

643 x 513 x 955 x 1 x 1 = 315015345

Therefore, the lowest common multiple of 513,955,643,643 is 315015345.

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.

513 x 955 x 643 x 643 = 202554866835

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.

513 : 1, 3, 9, 19, 27, 57, 171, 513

955 : 1, 5, 191, 955

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 513,955,643,643, is 1.

Now, the common factors can be found like this.

513:3x 3x 3x 19

955:5x 191

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.

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 = 202554866835/(1x643)

LCM = 202554866835/643

LCM = 315015345

Thus, we can understand that the LCM of 513,955,643,643 is 315015345.
