Given numbers are 643,166,176,906,286

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

The LCM of 643,166,176,906,286 is 55315047216.

Find LCM of 643,166,176,906,286 with Prime Factorization

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

2 x 11 x 643 x 83 x 8 x 453 x 13 = 55315047216

Therefore, the lowest common multiple of 643,166,176,906,286 is 55315047216.

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.

643 x 166 x 176 x 906 x 286 = 4867724155008

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.

643 : 1, 643

166 : 1, 2, 83, 166

176 : 1, 2, 4, 8, 11, 16, 22, 44, 88, 176

906 : 1, 2, 3, 6, 151, 302, 453, 906

286 : 1, 2, 11, 13, 22, 26, 143, 286

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 643,166,176,906,286, is 1.

Now, the common factors can be found like this.

643:643

166:2x 83

176:2x 2x 2x 2x 11

906:2x 3x 151

286:2x 11x 13

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

2x 2x 2x 11 = 88

Therefore, the value for common factors is 88.

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 = 4867724155008/(1x88)

LCM = 4867724155008/88

LCM = 55315047216

Thus, we can understand that the LCM of 643,166,176,906,286 is 55315047216.
