Given numbers are 731,387,645,503

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

The LCM of 731,387,645,503 is 16546185.

Find LCM of 731,387,645,503 with Prime Factorization

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

3 x 43 x 17 x 3 x 5 x 503 = 16546185

Therefore, the lowest common multiple of 731,387,645,503 is 16546185.

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.

731 x 387 x 645 x 503 = 91781688195

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.

731 : 1, 17, 43, 731

387 : 1, 3, 9, 43, 129, 387

645 : 1, 3, 5, 15, 43, 129, 215, 645

503 : 1, 503

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 731,387,645,503, is 1.

Now, the common factors can be found like this.

731:17x 43

387:3x 3x 43

645:3x 5x 43

503:503

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

3x 43x 43 = 5547

Therefore, the value for common factors is 5547.

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 = 91781688195/(1x5547)

LCM = 91781688195/5547

LCM = 16546185

Thus, we can understand that the LCM of 731,387,645,503 is 16546185.
