Given numbers are 185,415,431,345

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

The LCM of 185,415,431,345 is 456642345.

Find LCM of 185,415,431,345 with Prime Factorization

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

5 x 37 x 83 x 431 x 69 = 456642345

Therefore, the lowest common multiple of 185,415,431,345 is 456642345.

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.

185 x 415 x 431 x 345 = 11416058625

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.

185 : 1, 5, 37, 185

415 : 1, 5, 83, 415

431 : 1, 431

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 185,415,431,345, is 1.

Now, the common factors can be found like this.

185:5x 37

415:5x 83

431:431

345:3x 5x 23

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 = 11416058625/(1x25)

LCM = 11416058625/25

LCM = 456642345

Thus, we can understand that the LCM of 185,415,431,345 is 456642345.
