Given numbers are 815,854,190,321

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

The LCM of 815,854,190,321 is 4244964990.

Find LCM of 815,854,190,321 with Prime Factorization

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

2 x 5 x 163 x 427 x 19 x 321 = 4244964990

Therefore, the lowest common multiple of 815,854,190,321 is 4244964990.

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.

815 x 854 x 190 x 321 = 42449649900

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.

815 : 1, 5, 163, 815

854 : 1, 2, 7, 14, 61, 122, 427, 854

190 : 1, 2, 5, 10, 19, 38, 95, 190

321 : 1, 3, 107, 321

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 815,854,190,321, is 1.

Now, the common factors can be found like this.

815:5x 163

854:2x 7x 61

190:2x 5x 19

321:3x 107

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

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 42449649900/(1x10)

LCM = 42449649900/10

LCM = 4244964990

Thus, we can understand that the LCM of 815,854,190,321 is 4244964990.
