Given numbers are 643,290,920,173,191

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

The LCM of 643,290,920,173,191 is 566860595320.

Find LCM of 643,290,920,173,191 with Prime Factorization

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

2 x 5 x 643 x 29 x 92 x 173 x 191 = 566860595320

Therefore, the lowest common multiple of 643,290,920,173,191 is 566860595320.

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.

643 x 290 x 920 x 173 x 191 = 5668605953200

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.

643 : 1, 643

290 : 1, 2, 5, 10, 29, 58, 145, 290

920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920

173 : 1, 173

191 : 1, 191

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 643,290,920,173,191, is 1.

Now, the common factors can be found like this.

643:643

290:2x 5x 29

920:2x 2x 2x 5x 23

173:173

191:191

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 = 5668605953200/(1x10)

LCM = 5668605953200/10

LCM = 566860595320

Thus, we can understand that the LCM of 643,290,920,173,191 is 566860595320.
