Given numbers are 830,204,638

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

The LCM of 830,204,638 is 27006540.

Find LCM of 830,204,638 with Prime Factorization

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

2 x 415 x 102 x 319 = 27006540

Therefore, the lowest common multiple of 830,204,638 is 27006540.

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 204 x 638 = 108026160

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

204 : 1, 2, 3, 4, 6, 12, 17, 34, 51, 68, 102, 204

638 : 1, 2, 11, 22, 29, 58, 319, 638

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 830,204,638, is 2.

Now, the common factors can be found like this.

830:2x 5x 83

204:2x 2x 3x 17

638:2x 11x 29

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

2 = 2

Therefore, the value for common factors is 2.

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 = 108026160/(2x2)

LCM = 108026160/4

LCM = 27006540

Thus, we can understand that the LCM of 830,204,638 is 27006540.
