Given numbers are 717,858,780,442,161

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

The LCM of 717,858,780,442,161 is 5612546940.

Find LCM of 717,858,780,442,161 with Prime Factorization

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

2 x 3 x 13 x 239 x 11 x 10 x 17 x 161 = 5612546940

Therefore, the lowest common multiple of 717,858,780,442,161 is 5612546940.

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.

717 x 858 x 780 x 442 x 161 = 34146735582960

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.

717 : 1, 3, 239, 717

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

780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780

442 : 1, 2, 13, 17, 26, 34, 221, 442

161 : 1, 7, 23, 161

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 717,858,780,442,161, is 1.

Now, the common factors can be found like this.

717:3x 239

858:2x 3x 11x 13

780:2x 2x 3x 5x 13

442:2x 13x 17

161:7x 23

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

2x 2x 3x 3x 13x 13 = 6084

Therefore, the value for common factors is 6084.

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 = 34146735582960/(1x6084)

LCM = 34146735582960/6084

LCM = 5612546940

Thus, we can understand that the LCM of 717,858,780,442,161 is 5612546940.
