Given numbers are 815,321,163,397,221

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

The LCM of 815,321,163,397,221 is 22953315255.

Find LCM of 815,321,163,397,221 with Prime Factorization

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

163 x 5 x 321 x 1 x 397 x 221 = 22953315255

Therefore, the lowest common multiple of 815,321,163,397,221 is 22953315255.

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 321 x 163 x 397 x 221 = 3741390386565

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

321 : 1, 3, 107, 321

163 : 1, 163

397 : 1, 397

221 : 1, 13, 17, 221

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 815,321,163,397,221, is 1.

Now, the common factors can be found like this.

815:5x 163

321:3x 107

163:163

397:397

221:13x 17

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

163 = 163

Therefore, the value for common factors is 163.

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 = 3741390386565/(1x163)

LCM = 3741390386565/163

LCM = 22953315255

Thus, we can understand that the LCM of 815,321,163,397,221 is 22953315255.
