Given numbers are 687,908,122,395,818

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

The LCM of 687,908,122,395,818 is 6147419129580.

Find LCM of 687,908,122,395,818 with Prime Factorization

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

2 x 687 x 454 x 61 x 395 x 409 = 6147419129580

Therefore, the lowest common multiple of 687,908,122,395,818 is 6147419129580.

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.

687 x 908 x 122 x 395 x 818 = 24589676518320

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.

687 : 1, 3, 229, 687

908 : 1, 2, 4, 227, 454, 908

122 : 1, 2, 61, 122

395 : 1, 5, 79, 395

818 : 1, 2, 409, 818

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 687,908,122,395,818, is 1.

Now, the common factors can be found like this.

687:3x 229

908:2x 2x 227

122:2x 61

395:5x 79

818:2x 409

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 = 24589676518320/(1x4)

LCM = 24589676518320/4

LCM = 6147419129580

Thus, we can understand that the LCM of 687,908,122,395,818 is 6147419129580.
