Given numbers are 818,133,858,842

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

The LCM of 818,133,858,842 is 19649175546.

Find LCM of 818,133,858,842 with Prime Factorization

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

2 x 409 x 133 x 429 x 421 = 19649175546

Therefore, the lowest common multiple of 818,133,858,842 is 19649175546.

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.

818 x 133 x 858 x 842 = 78596702184

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.

818 : 1, 2, 409, 818

133 : 1, 7, 19, 133

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

842 : 1, 2, 421, 842

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 818,133,858,842, is 1.

Now, the common factors can be found like this.

818:2x 409

133:7x 19

858:2x 3x 11x 13

842:2x 421

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 = 78596702184/(1x4)

LCM = 78596702184/4

LCM = 19649175546

Thus, we can understand that the LCM of 818,133,858,842 is 19649175546.
