Given numbers are 249,711,687

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

The LCM of 249,711,687 is 13513977.

Find LCM of 249,711,687 with Prime Factorization

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

3 x 83 x 237 x 229 = 13513977

Therefore, the lowest common multiple of 249,711,687 is 13513977.

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.

249 x 711 x 687 = 121625793

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.

249 : 1, 3, 83, 249

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

687 : 1, 3, 229, 687

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 249,711,687, is 3.

Now, the common factors can be found like this.

249:3x 83

711:3x 3x 79

687:3x 229

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 = 121625793/(3x3)

LCM = 121625793/9

LCM = 13513977

Thus, we can understand that the LCM of 249,711,687 is 13513977.

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

• LCM of 997, 517, 654
• LCM of 662, 838, 250
