Given numbers are 291,380,618,489,213

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

The LCM of 291,380,618,489,213 is 131813461020.

Find LCM of 291,380,618,489,213 with Prime Factorization

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

2 x 3 x 97 x 190 x 103 x 163 x 71 = 131813461020

Therefore, the lowest common multiple of 291,380,618,489,213 is 131813461020.

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 380 x 618 x 489 x 213 = 7117926895080

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

380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380

618 : 1, 2, 3, 6, 103, 206, 309, 618

489 : 1, 3, 163, 489

213 : 1, 3, 71, 213

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 291,380,618,489,213, is 1.

Now, the common factors can be found like this.

291:3x 97

380:2x 2x 5x 19

618:2x 3x 103

489:3x 163

213:3x 71

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

2x 3x 3x 3 = 54

Therefore, the value for common factors is 54.

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 = 7117926895080/(1x54)

LCM = 7117926895080/54

LCM = 131813461020

Thus, we can understand that the LCM of 291,380,618,489,213 is 131813461020.
