Calculate the LCM of 858,969,847,817

Given numbers are 858,969,847,817

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

The LCM of 858,969,847,817 is 917590674.

Find LCM of 858,969,847,817 with Prime Factorization


3 858, 969, 847, 817
11 286, 323, 847, 817
19 26, 323, 77, 817
26, 17, 77, 43

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

3 x 11 x 19 x 26 x 17 x 77 x 43 = 917590674

Therefore, the lowest common multiple of 858,969,847,817 is 917590674.

LCM Formula to Find Lowest Common Multiple of 858,969,847,817

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.

858 x 969 x 847 x 817 = 575329352598

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.

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

969 : 1, 3, 17, 19, 51, 57, 323, 969

847 : 1, 7, 11, 77, 121, 847

817 : 1, 19, 43, 817

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 858,969,847,817, is 1.

Now, the common factors can be found like this.

858:2x 3x 11x 13

969:3x 17x 19

847:7x 11x 11

817:19x 43

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

3x 11x 19 = 627

Therefore, the value for common factors is 627.

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 = 575329352598/(1x627)

LCM = 575329352598/627

LCM = 917590674

Thus, we can understand that the LCM of 858,969,847,817 is 917590674.
