Given numbers are 831,213,138,629

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

The LCM of 831,213,138,629 is 1707134934.

Find LCM of 831,213,138,629 with Prime Factorization

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

3 x 277 x 71 x 46 x 629 = 1707134934

Therefore, the lowest common multiple of 831,213,138,629 is 1707134934.

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 213 x 138 x 629 = 15364214406

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

213 : 1, 3, 71, 213

138 : 1, 2, 3, 6, 23, 46, 69, 138

629 : 1, 17, 37, 629

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 831,213,138,629, is 1.

Now, the common factors can be found like this.

831:3x 277

213:3x 71

138:2x 3x 23

629:17x 37

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 = 15364214406/(1x9)

LCM = 15364214406/9

LCM = 1707134934

Thus, we can understand that the LCM of 831,213,138,629 is 1707134934.
