Given numbers are 249,856,813,581

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

The LCM of 249,856,813,581 is 404334168.

Find LCM of 249,856,813,581 with Prime Factorization

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

3 x 83 x 1 x 856 x 271 x 7 = 404334168

Therefore, the lowest common multiple of 249,856,813,581 is 404334168.

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 856 x 813 x 581 = 100679207832

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

856 : 1, 2, 4, 8, 107, 214, 428, 856

813 : 1, 3, 271, 813

581 : 1, 7, 83, 581

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 249,856,813,581, is 1.

Now, the common factors can be found like this.

249:3x 83

856:2x 2x 2x 107

813:3x 271

581:7x 83

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

3x 83 = 249

Therefore, the value for common factors is 249.

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 = 100679207832/(1x249)

LCM = 100679207832/249

LCM = 404334168

Thus, we can understand that the LCM of 249,856,813,581 is 404334168.
