Given numbers are 815,230,422,743

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

The LCM of 815,230,422,743 is 5877419770.

Find LCM of 815,230,422,743 with Prime Factorization

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

2 x 5 x 163 x 23 x 211 x 743 = 5877419770

Therefore, the lowest common multiple of 815,230,422,743 is 5877419770.

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 230 x 422 x 743 = 58774197700

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

230 : 1, 2, 5, 10, 23, 46, 115, 230

422 : 1, 2, 211, 422

743 : 1, 743

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 815,230,422,743, is 1.

Now, the common factors can be found like this.

815:5x 163

230:2x 5x 23

422:2x 211

743:743

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 = 58774197700/(1x10)

LCM = 58774197700/10

LCM = 5877419770

Thus, we can understand that the LCM of 815,230,422,743 is 5877419770.
