Given numbers are 515,422,644,286

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

The LCM of 515,422,644,286 is 10007177180.

Find LCM of 515,422,644,286 with Prime Factorization

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

2 x 515 x 211 x 322 x 143 = 10007177180

Therefore, the lowest common multiple of 515,422,644,286 is 10007177180.

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.

515 x 422 x 644 x 286 = 40028708720

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.

515 : 1, 5, 103, 515

422 : 1, 2, 211, 422

644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644

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 515,422,644,286, is 1.

Now, the common factors can be found like this.

515:5x 103

422:2x 211

644:2x 2x 7x 23

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 = 40028708720/(1x4)

LCM = 40028708720/4

LCM = 10007177180

Thus, we can understand that the LCM of 515,422,644,286 is 10007177180.
