Given numbers are 345,545,215,410,731

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

The LCM of 345,545,215,410,731 is 2254118910.

Find LCM of 345,545,215,410,731 with Prime Factorization

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

5 x 43 x 69 x 109 x 1 x 82 x 17 = 2254118910

Therefore, the lowest common multiple of 345,545,215,410,731 is 2254118910.

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.

345 x 545 x 215 x 410 x 731 = 12115889141250

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.

345 : 1, 3, 5, 15, 23, 69, 115, 345

545 : 1, 5, 109, 545

215 : 1, 5, 43, 215

410 : 1, 2, 5, 10, 41, 82, 205, 410

731 : 1, 17, 43, 731

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 345,545,215,410,731, is 1.

Now, the common factors can be found like this.

345:3x 5x 23

545:5x 109

215:5x 43

410:2x 5x 41

731:17x 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 5x 5x 43 = 5375

Therefore, the value for common factors is 5375.

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 = 12115889141250/(1x5375)

LCM = 12115889141250/5375

LCM = 2254118910

Thus, we can understand that the LCM of 345,545,215,410,731 is 2254118910.
