Given numbers are 636,815,146,215

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

The LCM of 636,815,146,215 is 1627069260.

Find LCM of 636,815,146,215 with Prime Factorization

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

2 x 5 x 318 x 163 x 73 x 43 = 1627069260

Therefore, the lowest common multiple of 636,815,146,215 is 1627069260.

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.

636 x 815 x 146 x 215 = 16270692600

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.

636 : 1, 2, 3, 4, 6, 12, 53, 106, 159, 212, 318, 636

815 : 1, 5, 163, 815

146 : 1, 2, 73, 146

215 : 1, 5, 43, 215

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 636,815,146,215, is 1.

Now, the common factors can be found like this.

636:2x 2x 3x 53

815:5x 163

146:2x 73

215:5x 43

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

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 16270692600/(1x10)

LCM = 16270692600/10

LCM = 1627069260

Thus, we can understand that the LCM of 636,815,146,215 is 1627069260.
