Given numbers are 247,821,858

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

The LCM of 247,821,858 is 13383942.

Find LCM of 247,821,858 with Prime Factorization

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

13 x 19 x 821 x 66 = 13383942

Therefore, the lowest common multiple of 247,821,858 is 13383942.

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.

247 x 821 x 858 = 173991246

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.

247 : 1, 13, 19, 247

821 : 1, 821

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 247,821,858, is 1.

Now, the common factors can be found like this.

247:13x 19

821:821

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.

13 = 13

Therefore, the value for common factors is 13.

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 = 173991246/(1x13)

LCM = 173991246/13

LCM = 13383942

Thus, we can understand that the LCM of 247,821,858 is 13383942.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 948, 345, 335
