Given numbers are 436,272,286,545

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

The LCM of 436,272,286,545 is 21198320.

Find LCM of 436,272,286,545 with Prime Factorization

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

2 x 2 x 109 x 1 x 68 x 143 x 5 = 21198320

Therefore, the lowest common multiple of 436,272,286,545 is 21198320.

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.

436 x 272 x 286 x 545 = 18484935040

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.

436 : 1, 2, 4, 109, 218, 436

272 : 1, 2, 4, 8, 16, 17, 34, 68, 136, 272

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

545 : 1, 5, 109, 545

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 436,272,286,545, is 1.

Now, the common factors can be found like this.

436:2x 2x 109

272:2x 2x 2x 2x 17

286:2x 11x 13

545:5x 109

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

2x 2x 2x 109 = 872

Therefore, the value for common factors is 872.

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 = 18484935040/(1x872)

LCM = 18484935040/872

LCM = 21198320

Thus, we can understand that the LCM of 436,272,286,545 is 21198320.
