Given numbers are 286,713,865,217

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

The LCM of 286,713,865,217 is 1234723490.

Find LCM of 286,713,865,217 with Prime Factorization

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

31 x 286 x 23 x 865 x 7 = 1234723490

Therefore, the lowest common multiple of 286,713,865,217 is 1234723490.

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.

286 x 713 x 865 x 217 = 38276428190

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.

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

713 : 1, 23, 31, 713

865 : 1, 5, 173, 865

217 : 1, 7, 31, 217

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 286,713,865,217, is 1.

Now, the common factors can be found like this.

286:2x 11x 13

713:23x 31

865:5x 173

217:7x 31

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

31 = 31

Therefore, the value for common factors is 31.

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 = 38276428190/(1x31)

LCM = 38276428190/31

LCM = 1234723490

Thus, we can understand that the LCM of 286,713,865,217 is 1234723490.
