Given numbers are 386,398,398,286

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

The LCM of 386,398,398,286 is 10984402.

Find LCM of 386,398,398,286 with Prime Factorization

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

2 x 199 x 193 x 1 x 1 x 143 = 10984402

Therefore, the lowest common multiple of 386,398,398,286 is 10984402.

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.

386 x 398 x 398 x 286 = 17487167984

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.

386 : 1, 2, 193, 386

398 : 1, 2, 199, 398

398 : 1, 2, 199, 398

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

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 386,398,398,286, is 2.

Now, the common factors can be found like this.

386:2x 193

398:2x 199

398:2x 199

286:2x 11x 13

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 199 = 796

Therefore, the value for common factors is 796.

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 = 17487167984/(2x796)

LCM = 17487167984/1592

LCM = 10984402

Thus, we can understand that the LCM of 386,398,398,286 is 10984402.
