Given numbers are 415,515,346,645

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

The LCM of 415,515,346,645 is 1907880330.

Find LCM of 415,515,346,645 with Prime Factorization

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

5 x 83 x 103 x 346 x 129 = 1907880330

Therefore, the lowest common multiple of 415,515,346,645 is 1907880330.

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.

415 x 515 x 346 x 645 = 47697008250

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.

415 : 1, 5, 83, 415

515 : 1, 5, 103, 515

346 : 1, 2, 173, 346

645 : 1, 3, 5, 15, 43, 129, 215, 645

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 415,515,346,645, is 1.

Now, the common factors can be found like this.

415:5x 83

515:5x 103

346:2x 173

645:3x 5x 43

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 = 47697008250/(1x25)

LCM = 47697008250/25

LCM = 1907880330

Thus, we can understand that the LCM of 415,515,346,645 is 1907880330.
