Given numbers are 291,828,523,642

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

The LCM of 291,828,523,642 is 4494563676.

Find LCM of 291,828,523,642 with Prime Factorization

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

2 x 3 x 97 x 138 x 523 x 107 = 4494563676

Therefore, the lowest common multiple of 291,828,523,642 is 4494563676.

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.

291 x 828 x 523 x 642 = 80902146168

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.

291 : 1, 3, 97, 291

828 : 1, 2, 3, 4, 6, 9, 12, 18, 23, 36, 46, 69, 92, 138, 207, 276, 414, 828

523 : 1, 523

642 : 1, 2, 3, 6, 107, 214, 321, 642

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 291,828,523,642, is 1.

Now, the common factors can be found like this.

291:3x 97

828:2x 2x 3x 3x 23

523:523

642:2x 3x 107

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

2x 3x 3 = 18

Therefore, the value for common factors is 18.

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 = 80902146168/(1x18)

LCM = 80902146168/18

LCM = 4494563676

Thus, we can understand that the LCM of 291,828,523,642 is 4494563676.
