Given numbers are 281,843,344,561

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

The LCM of 281,843,344,561 is 54228504.

Find LCM of 281,843,344,561 with Prime Factorization

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

3 x 281 x 1 x 1 x 344 x 187 = 54228504

Therefore, the lowest common multiple of 281,843,344,561 is 54228504.

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.

281 x 843 x 344 x 561 = 45714628872

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.

281 : 1, 281

843 : 1, 3, 281, 843

344 : 1, 2, 4, 8, 43, 86, 172, 344

561 : 1, 3, 11, 17, 33, 51, 187, 561

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 281,843,344,561, is 1.

Now, the common factors can be found like this.

281:281

843:3x 281

344:2x 2x 2x 43

561:3x 11x 17

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

3x 281 = 843

Therefore, the value for common factors is 843.

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 = 45714628872/(1x843)

LCM = 45714628872/843

LCM = 54228504

Thus, we can understand that the LCM of 281,843,344,561 is 54228504.
