Given numbers are 639,386,578,286

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

The LCM of 639,386,578,286 is 10193469858.

Find LCM of 639,386,578,286 with Prime Factorization

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

2 x 639 x 193 x 289 x 143 = 10193469858

Therefore, the lowest common multiple of 639,386,578,286 is 10193469858.

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.

639 x 386 x 578 x 286 = 40773879432

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.

639 : 1, 3, 9, 71, 213, 639

386 : 1, 2, 193, 386

578 : 1, 2, 17, 34, 289, 578

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 639,386,578,286, is 1.

Now, the common factors can be found like this.

639:3x 3x 71

386:2x 193

578:2x 17x 17

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 2 = 4

Therefore, the value for common factors is 4.

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 = 40773879432/(1x4)

LCM = 40773879432/4

LCM = 10193469858

Thus, we can understand that the LCM of 639,386,578,286 is 10193469858.
