Given numbers are 215,428,286,555

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

The LCM of 215,428,286,555 is 1460633460.

Find LCM of 215,428,286,555 with Prime Factorization

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

2 x 5 x 43 x 214 x 143 x 111 = 1460633460

Therefore, the lowest common multiple of 215,428,286,555 is 1460633460.

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.

215 x 428 x 286 x 555 = 14606334600

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.

215 : 1, 5, 43, 215

428 : 1, 2, 4, 107, 214, 428

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

555 : 1, 3, 5, 15, 37, 111, 185, 555

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 215,428,286,555, is 1.

Now, the common factors can be found like this.

215:5x 43

428:2x 2x 107

286:2x 11x 13

555:3x 5x 37

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

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 14606334600/(1x10)

LCM = 14606334600/10

LCM = 1460633460

Thus, we can understand that the LCM of 215,428,286,555 is 1460633460.
