Given numbers are 813,801,318,987

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

The LCM of 813,801,318,987 is 7570134054.

Find LCM of 813,801,318,987 with Prime Factorization

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

3 x 271 x 267 x 106 x 329 = 7570134054

Therefore, the lowest common multiple of 813,801,318,987 is 7570134054.

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.

813 x 801 x 318 x 987 = 204393619458

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.

813 : 1, 3, 271, 813

801 : 1, 3, 9, 89, 267, 801

318 : 1, 2, 3, 6, 53, 106, 159, 318

987 : 1, 3, 7, 21, 47, 141, 329, 987

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 813,801,318,987, is 3.

Now, the common factors can be found like this.

813:3x 271

801:3x 3x 89

318:2x 3x 53

987:3x 7x 47

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

3x 3 = 9

Therefore, the value for common factors is 9.

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 = 204393619458/(3x9)

LCM = 204393619458/27

LCM = 7570134054

Thus, we can understand that the LCM of 813,801,318,987 is 7570134054.
