Given numbers are 867,173,423

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

The LCM of 867,173,423 is 21148731.

Find LCM of 867,173,423 with Prime Factorization

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

3 x 289 x 173 x 141 = 21148731

Therefore, the lowest common multiple of 867,173,423 is 21148731.

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.

867 x 173 x 423 = 63446193

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.

867 : 1, 3, 17, 51, 289, 867

173 : 1, 173

423 : 1, 3, 9, 47, 141, 423

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 867,173,423, is 1.

Now, the common factors can be found like this.

867:3x 17x 17

173:173

423:3x 3x 47

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

3 = 3

Therefore, the value for common factors is 3.

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 = 63446193/(1x3)

LCM = 63446193/3

LCM = 21148731

Thus, we can understand that the LCM of 867,173,423 is 21148731.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 927, 162, 422
• LCM of 266, 119, 150
