Given numbers are 831,691,841,987

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

The LCM of 831,691,841,987 is 158880634269.

Find LCM of 831,691,841,987 with Prime Factorization

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

3 x 277 x 691 x 841 x 329 = 158880634269

Therefore, the lowest common multiple of 831,691,841,987 is 158880634269.

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.

831 x 691 x 841 x 987 = 476641902807

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.

831 : 1, 3, 277, 831

691 : 1, 691

841 : 1, 29, 841

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 831,691,841,987, is 1.

Now, the common factors can be found like this.

831:3x 277

691:691

841:29x 29

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.

3 = 3

Therefore, the value for common factors is 3.

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 = 476641902807/(1x3)

LCM = 476641902807/3

LCM = 158880634269

Thus, we can understand that the LCM of 831,691,841,987 is 158880634269.
