Given numbers are 215,245,515,422

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

The LCM of 215,245,515,422 is 457914310.

Find LCM of 215,245,515,422 with Prime Factorization

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

5 x 43 x 49 x 103 x 422 = 457914310

Therefore, the lowest common multiple of 215,245,515,422 is 457914310.

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 245 x 515 x 422 = 11447857750

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

245 : 1, 5, 7, 35, 49, 245

515 : 1, 5, 103, 515

422 : 1, 2, 211, 422

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 215,245,515,422, is 1.

Now, the common factors can be found like this.

215:5x 43

245:5x 7x 7

515:5x 103

422:2x 211

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

5x 5 = 25

Therefore, the value for common factors is 25.

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 = 11447857750/(1x25)

LCM = 11447857750/25

LCM = 457914310

Thus, we can understand that the LCM of 215,245,515,422 is 457914310.
