Given numbers are 286,311,311,515

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

The LCM of 286,311,311,515 is 45807190.

Find LCM of 286,311,311,515 with Prime Factorization

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

311 x 286 x 1 x 1 x 515 = 45807190

Therefore, the lowest common multiple of 286,311,311,515 is 45807190.

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 311 x 311 x 515 = 14246036090

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

311 : 1, 311

311 : 1, 311

515 : 1, 5, 103, 515

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 286,311,311,515, is 1.

Now, the common factors can be found like this.

286:2x 11x 13

311:311

311:311

515:5x 103

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

311 = 311

Therefore, the value for common factors is 311.

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 = 14246036090/(1x311)

LCM = 14246036090/311

LCM = 45807190

Thus, we can understand that the LCM of 286,311,311,515 is 45807190.
