Given numbers are 866,218,688,407

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

The LCM of 866,218,688,407 is 13215915152.

Find LCM of 866,218,688,407 with Prime Factorization

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

2 x 433 x 109 x 344 x 407 = 13215915152

Therefore, the lowest common multiple of 866,218,688,407 is 13215915152.

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.

866 x 218 x 688 x 407 = 52863660608

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.

866 : 1, 2, 433, 866

218 : 1, 2, 109, 218

688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688

407 : 1, 11, 37, 407

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 866,218,688,407, is 1.

Now, the common factors can be found like this.

866:2x 433

218:2x 109

688:2x 2x 2x 2x 43

407:11x 37

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 = 52863660608/(1x4)

LCM = 52863660608/4

LCM = 13215915152

Thus, we can understand that the LCM of 866,218,688,407 is 13215915152.
