Given numbers are 345,915,668,855,630

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

The LCM of 345,915,668,855,630 is 5609165940.

Find LCM of 345,915,668,855,630 with Prime Factorization

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

2 x 3 x 3 x 5 x 23 x 61 x 334 x 19 x 7 = 5609165940

Therefore, the lowest common multiple of 345,915,668,855,630 is 5609165940.

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.

345 x 915 x 668 x 855 x 630 = 113585610285000

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.

345 : 1, 3, 5, 15, 23, 69, 115, 345

915 : 1, 3, 5, 15, 61, 183, 305, 915

668 : 1, 2, 4, 167, 334, 668

855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855

630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 345,915,668,855,630, is 1.

Now, the common factors can be found like this.

345:3x 5x 23

915:3x 5x 61

668:2x 2x 167

855:3x 3x 5x 19

630:2x 3x 3x 5x 7

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

2x 3x 3x 3x 3x 5x 5x 5 = 20250

Therefore, the value for common factors is 20250.

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 = 113585610285000/(1x20250)

LCM = 113585610285000/20250

LCM = 5609165940

Thus, we can understand that the LCM of 345,915,668,855,630 is 5609165940.
