Given numbers are 815,403,403,386

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

The LCM of 815,403,403,386 is 126779770.

Find LCM of 815,403,403,386 with Prime Factorization

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

13 x 31 x 815 x 1 x 1 x 386 = 126779770

Therefore, the lowest common multiple of 815,403,403,386 is 126779770.

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 403 x 403 x 386 = 51092247310

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

403 : 1, 13, 31, 403

403 : 1, 13, 31, 403

386 : 1, 2, 193, 386

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 815,403,403,386, is 1.

Now, the common factors can be found like this.

815:5x 163

403:13x 31

403:13x 31

386:2x 193

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

13x 31 = 403

Therefore, the value for common factors is 403.

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 = 51092247310/(1x403)

LCM = 51092247310/403

LCM = 126779770

Thus, we can understand that the LCM of 815,403,403,386 is 126779770.
