Given numbers are 687,498,791,831

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

The LCM of 687,498,791,831 is 24987400494.

Find LCM of 687,498,791,831 with Prime Factorization

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

3 x 229 x 166 x 791 x 277 = 24987400494

Therefore, the lowest common multiple of 687,498,791,831 is 24987400494.

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.

687 x 498 x 791 x 831 = 224886604446

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.

687 : 1, 3, 229, 687

498 : 1, 2, 3, 6, 83, 166, 249, 498

791 : 1, 7, 113, 791

831 : 1, 3, 277, 831

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 687,498,791,831, is 1.

Now, the common factors can be found like this.

687:3x 229

498:2x 3x 83

791:7x 113

831:3x 277

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 = 224886604446/(1x9)

LCM = 224886604446/9

LCM = 24987400494

Thus, we can understand that the LCM of 687,498,791,831 is 24987400494.
