Given numbers are 687,581,711

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

The LCM of 687,581,711 is 94597839.

Find LCM of 687,581,711 with Prime Factorization

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

3 x 229 x 581 x 237 = 94597839

Therefore, the lowest common multiple of 687,581,711 is 94597839.

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.

687 x 581 x 711 = 283793517

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.

687 : 1, 3, 229, 687

581 : 1, 7, 83, 581

711 : 1, 3, 9, 79, 237, 711

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 687,581,711, is 1.

Now, the common factors can be found like this.

687:3x 229

581:7x 83

711:3x 3x 79

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 = 283793517/(1x3)

LCM = 283793517/3

LCM = 94597839

Thus, we can understand that the LCM of 687,581,711 is 94597839.

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

• LCM of 432, 408, 237
• LCM of 435, 415, 814
