Given numbers are 247,647,284,894

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

The LCM of 247,647,284,894 is 20287432932.

Find LCM of 247,647,284,894 with Prime Factorization

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

2 x 247 x 647 x 142 x 447 = 20287432932

Therefore, the lowest common multiple of 247,647,284,894 is 20287432932.

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.

247 x 647 x 284 x 894 = 40574865864

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.

247 : 1, 13, 19, 247

647 : 1, 647

284 : 1, 2, 4, 71, 142, 284

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 247,647,284,894, is 1.

Now, the common factors can be found like this.

247:13x 19

647:647

284:2x 2x 71

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.

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 = 40574865864/(1x2)

LCM = 40574865864/2

LCM = 20287432932

Thus, we can understand that the LCM of 247,647,284,894 is 20287432932.
