Given numbers are 645,522,759,447

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

The LCM of 645,522,759,447 is 4230734310.

Find LCM of 645,522,759,447 with Prime Factorization

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

3 x 215 x 174 x 253 x 149 = 4230734310

Therefore, the lowest common multiple of 645,522,759,447 is 4230734310.

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.

645 x 522 x 759 x 447 = 114229826370

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.

645 : 1, 3, 5, 15, 43, 129, 215, 645

522 : 1, 2, 3, 6, 9, 18, 29, 58, 87, 174, 261, 522

759 : 1, 3, 11, 23, 33, 69, 253, 759

447 : 1, 3, 149, 447

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 645,522,759,447, is 3.

Now, the common factors can be found like this.

645:3x 5x 43

522:2x 3x 3x 29

759:3x 11x 23

447:3x 149

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

3x 3 = 9

Therefore, the value for common factors is 9.

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 = 114229826370/(3x9)

LCM = 114229826370/27

LCM = 4230734310

Thus, we can understand that the LCM of 645,522,759,447 is 4230734310.
