Given numbers are 247,166,855,388

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

The LCM of 247,166,855,388 is 357947460.

Find LCM of 247,166,855,388 with Prime Factorization

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

2 x 19 x 13 x 83 x 45 x 194 = 357947460

Therefore, the lowest common multiple of 247,166,855,388 is 357947460.

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 166 x 855 x 388 = 13602003480

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

166 : 1, 2, 83, 166

855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855

388 : 1, 2, 4, 97, 194, 388

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 247,166,855,388, is 1.

Now, the common factors can be found like this.

247:13x 19

166:2x 83

855:3x 3x 5x 19

388:2x 2x 97

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

2x 19 = 38

Therefore, the value for common factors is 38.

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 = 13602003480/(1x38)

LCM = 13602003480/38

LCM = 357947460

Thus, we can understand that the LCM of 247,166,855,388 is 357947460.
