Calculate the LCM of 831,395,288,487

Given numbers are 831,395,288,487

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

The LCM of 831,395,288,487 is 15346110240.

Find LCM of 831,395,288,487 with Prime Factorization


3 831, 395, 288, 487
277, 395, 96, 487

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

3 x 277 x 395 x 96 x 487 = 15346110240

Therefore, the lowest common multiple of 831,395,288,487 is 15346110240.

LCM Formula to Find Lowest Common Multiple of 831,395,288,487

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 395 x 288 x 487 = 46038330720

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

395 : 1, 5, 79, 395

288 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 72, 96, 144, 288

487 : 1, 487

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 831,395,288,487, is 1.

Now, the common factors can be found like this.

831:3x 277

395:5x 79

288:2x 2x 2x 2x 2x 3x 3

487:487

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 = 46038330720/(1x3)

LCM = 46038330720/3

LCM = 15346110240

Thus, we can understand that the LCM of 831,395,288,487 is 15346110240.
