Given numbers are 445,394,868,291

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

The LCM of 445,394,868,291 is 22143127020.

Find LCM of 445,394,868,291 with Prime Factorization

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

2 x 445 x 197 x 434 x 291 = 22143127020

Therefore, the lowest common multiple of 445,394,868,291 is 22143127020.

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.

445 x 394 x 868 x 291 = 44286254040

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.

445 : 1, 5, 89, 445

394 : 1, 2, 197, 394

868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868

291 : 1, 3, 97, 291

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 445,394,868,291, is 1.

Now, the common factors can be found like this.

445:5x 89

394:2x 197

868:2x 2x 7x 31

291:3x 97

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

2 = 2

Therefore, the value for common factors is 2.

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 = 44286254040/(1x2)

LCM = 44286254040/2

LCM = 22143127020

Thus, we can understand that the LCM of 445,394,868,291 is 22143127020.
