Given numbers are 173,221,963,321

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

The LCM of 173,221,963,321 is 36818379.

Find LCM of 173,221,963,321 with Prime Factorization

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

3 x 107 x 173 x 221 x 3 x 1 = 36818379

Therefore, the lowest common multiple of 173,221,963,321 is 36818379.

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.

173 x 221 x 963 x 321 = 11818699659

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.

173 : 1, 173

221 : 1, 13, 17, 221

963 : 1, 3, 9, 107, 321, 963

321 : 1, 3, 107, 321

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 173,221,963,321, is 1.

Now, the common factors can be found like this.

173:173

221:13x 17

963:3x 3x 107

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.

3x 107 = 321

Therefore, the value for common factors is 321.

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 = 11818699659/(1x321)

LCM = 11818699659/321

LCM = 36818379

Thus, we can understand that the LCM of 173,221,963,321 is 36818379.
