Given numbers are 687,164,497,858

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

The LCM of 687,164,497,858 is 8007427428.

Find LCM of 687,164,497,858 with Prime Factorization

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

2 x 3 x 229 x 82 x 497 x 143 = 8007427428

Therefore, the lowest common multiple of 687,164,497,858 is 8007427428.

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 164 x 497 x 858 = 48044564568

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

164 : 1, 2, 4, 41, 82, 164

497 : 1, 7, 71, 497

858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 687,164,497,858, is 1.

Now, the common factors can be found like this.

687:3x 229

164:2x 2x 41

497:7x 71

858:2x 3x 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 3 = 6

Therefore, the value for common factors is 6.

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 = 48044564568/(1x6)

LCM = 48044564568/6

LCM = 8007427428

Thus, we can understand that the LCM of 687,164,497,858 is 8007427428.
