Given numbers are 815,669,203,815

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

The LCM of 815,669,203,815 is 110682705.

Find LCM of 815,669,203,815 with Prime Factorization

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

5 x 163 x 1 x 669 x 203 x 1 = 110682705

Therefore, the lowest common multiple of 815,669,203,815 is 110682705.

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.

815 x 669 x 203 x 815 = 90206404575

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.

815 : 1, 5, 163, 815

669 : 1, 3, 223, 669

203 : 1, 7, 29, 203

815 : 1, 5, 163, 815

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 815,669,203,815, is 1.

Now, the common factors can be found like this.

815:5x 163

669:3x 223

203:7x 29

815:5x 163

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

5x 163 = 815

Therefore, the value for common factors is 815.

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 = 90206404575/(1x815)

LCM = 90206404575/815

LCM = 110682705

Thus, we can understand that the LCM of 815,669,203,815 is 110682705.
