Given numbers are 422,173,860,115

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

The LCM of 422,173,860,115 is 722029340.

Find LCM of 422,173,860,115 with Prime Factorization

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

2 x 5 x 211 x 173 x 86 x 23 = 722029340

Therefore, the lowest common multiple of 422,173,860,115 is 722029340.

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.

422 x 173 x 860 x 115 = 7220293400

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.

422 : 1, 2, 211, 422

173 : 1, 173

860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860

115 : 1, 5, 23, 115

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 422,173,860,115, is 1.

Now, the common factors can be found like this.

422:2x 211

173:173

860:2x 2x 5x 43

115:5x 23

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

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 7220293400/(1x10)

LCM = 7220293400/10

LCM = 722029340

Thus, we can understand that the LCM of 422,173,860,115 is 722029340.
