Given numbers are 815,344,129,145

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

The LCM of 815,344,129,145 is 24391320.

Find LCM of 815,344,129,145 with Prime Factorization

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

5 x 43 x 163 x 8 x 3 x 29 = 24391320

Therefore, the lowest common multiple of 815,344,129,145 is 24391320.

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 344 x 129 x 145 = 5244133800

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

344 : 1, 2, 4, 8, 43, 86, 172, 344

129 : 1, 3, 43, 129

145 : 1, 5, 29, 145

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 815,344,129,145, is 1.

Now, the common factors can be found like this.

815:5x 163

344:2x 2x 2x 43

129:3x 43

145:5x 29

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

5x 43 = 215

Therefore, the value for common factors is 215.

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 = 5244133800/(1x215)

LCM = 5244133800/215

LCM = 24391320

Thus, we can understand that the LCM of 815,344,129,145 is 24391320.
