Given numbers are 2,800,394,894

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

The LCM of 2,800,394,894 is 70447200.

Find LCM of 2,800,394,894 with Prime Factorization

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

2 x 1 x 400 x 197 x 447 = 70447200

Therefore, the lowest common multiple of 2,800,394,894 is 70447200.

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.

2 x 800 x 394 x 894 = 563577600

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.

2 : 1, 2

800 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 32, 40, 50, 80, 100, 160, 200, 400, 800

394 : 1, 2, 197, 394

894 : 1, 2, 3, 6, 149, 298, 447, 894

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 2,800,394,894, is 2.

Now, the common factors can be found like this.

2:2

800:2x 2x 2x 2x 2x 5x 5

394:2x 197

894:2x 3x 149

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 563577600/(2x4)

LCM = 563577600/8

LCM = 70447200

Thus, we can understand that the LCM of 2,800,394,894 is 70447200.
