Given numbers are 6447,1881

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

The LCM of 6447,1881 is 4042269.

Find LCM of 6447,1881 with Prime Factorization

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

3 x 2149 x 627 = 4042269

Therefore, the lowest common multiple of 6447,1881 is 4042269.

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.

6447 x 1881 = 12126807

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.

6447 : 1, 3, 7, 21, 307, 921, 2149, 6447

1881 : 1, 3, 9, 11, 19, 33, 57, 99, 171, 209, 627, 1881

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 6447,1881, is 3.

Now, the common factors can be found like this.

6447:3x 7x 307

1881:3x 3x 11x 19

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

= 1

Therefore, the value for common factors is 1.

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 = 12126807/(3x1)

LCM = 12126807/3

LCM = 4042269

Thus, we can understand that the LCM of 6447,1881 is 4042269.
