Given numbers are 381,171,691

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

The LCM of 381,171,691 is 15006447.

Find LCM of 381,171,691 with Prime Factorization

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

3 x 127 x 57 x 691 = 15006447

Therefore, the lowest common multiple of 381,171,691 is 15006447.

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.

381 x 171 x 691 = 45019341

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.

381 : 1, 3, 127, 381

171 : 1, 3, 9, 19, 57, 171

691 : 1, 691

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 381,171,691, is 1.

Now, the common factors can be found like this.

381:3x 127

171:3x 3x 19

691:691

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 = 45019341/(1x3)

LCM = 45019341/3

LCM = 15006447

Thus, we can understand that the LCM of 381,171,691 is 15006447.

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

• LCM of 701, 227, 900
• LCM of 527, 496, 131
