Given numbers are 830,166,391,403

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

The LCM of 830,166,391,403 is 130785590.

Find LCM of 830,166,391,403 with Prime Factorization

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

2 x 83 x 5 x 1 x 391 x 403 = 130785590

Therefore, the lowest common multiple of 830,166,391,403 is 130785590.

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.

830 x 166 x 391 x 403 = 21710407940

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.

830 : 1, 2, 5, 10, 83, 166, 415, 830

166 : 1, 2, 83, 166

391 : 1, 17, 23, 391

403 : 1, 13, 31, 403

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 830,166,391,403, is 1.

Now, the common factors can be found like this.

830:2x 5x 83

166:2x 83

391:17x 23

403:13x 31

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

2x 83 = 166

Therefore, the value for common factors is 166.

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 = 21710407940/(1x166)

LCM = 21710407940/166

LCM = 130785590

Thus, we can understand that the LCM of 830,166,391,403 is 130785590.
