Given numbers are 831,554,286,581

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

The LCM of 831,554,286,581 is 138083946.

Find LCM of 831,554,286,581 with Prime Factorization

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

2 x 277 x 3 x 1 x 143 x 581 = 138083946

Therefore, the lowest common multiple of 831,554,286,581 is 138083946.

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.

831 x 554 x 286 x 581 = 76498506084

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.

831 : 1, 3, 277, 831

554 : 1, 2, 277, 554

286 : 1, 2, 11, 13, 22, 26, 143, 286

581 : 1, 7, 83, 581

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 831,554,286,581, is 1.

Now, the common factors can be found like this.

831:3x 277

554:2x 277

286:2x 11x 13

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.

2x 277 = 554

Therefore, the value for common factors is 554.

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 = 76498506084/(1x554)

LCM = 76498506084/554

LCM = 138083946

Thus, we can understand that the LCM of 831,554,286,581 is 138083946.
