Given numbers are 291,580,982,221

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

The LCM of 291,580,982,221 is 18314486580.

Find LCM of 291,580,982,221 with Prime Factorization

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

2 x 291 x 290 x 491 x 221 = 18314486580

Therefore, the lowest common multiple of 291,580,982,221 is 18314486580.

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.

291 x 580 x 982 x 221 = 36628973160

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.

291 : 1, 3, 97, 291

580 : 1, 2, 4, 5, 10, 20, 29, 58, 116, 145, 290, 580

982 : 1, 2, 491, 982

221 : 1, 13, 17, 221

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 291,580,982,221, is 1.

Now, the common factors can be found like this.

291:3x 97

580:2x 2x 5x 29

982:2x 491

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.

2 = 2

Therefore, the value for common factors is 2.

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 = 36628973160/(1x2)

LCM = 36628973160/2

LCM = 18314486580

Thus, we can understand that the LCM of 291,580,982,221 is 18314486580.
