Given numbers are 540,643,103,247,831

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

The LCM of 540,643,103,247,831 is 2446913853540.

Find LCM of 540,643,103,247,831 with Prime Factorization

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

3 x 180 x 643 x 103 x 247 x 277 = 2446913853540

Therefore, the lowest common multiple of 540,643,103,247,831 is 2446913853540.

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.

540 x 643 x 103 x 247 x 831 = 7340741560620

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.

540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540

643 : 1, 643

103 : 1, 103

247 : 1, 13, 19, 247

831 : 1, 3, 277, 831

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 540,643,103,247,831, is 1.

Now, the common factors can be found like this.

540:2x 2x 3x 3x 3x 5

643:643

103:103

247:13x 19

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.

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 = 7340741560620/(1x3)

LCM = 7340741560620/3

LCM = 2446913853540

Thus, we can understand that the LCM of 540,643,103,247,831 is 2446913853540.
