Given numbers are 281,281,649,449

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

The LCM of 281,281,649,449 is 81883681.

Find LCM of 281,281,649,449 with Prime Factorization

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

281 x 1 x 1 x 649 x 449 = 81883681

Therefore, the lowest common multiple of 281,281,649,449 is 81883681.

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 281 x 649 x 449 = 23009314361

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

281 : 1, 281

649 : 1, 11, 59, 649

449 : 1, 449

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 281,281,649,449, is 1.

Now, the common factors can be found like this.

281:281

281:281

649:11x 59

449:449

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

281 = 281

Therefore, the value for common factors is 281.

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 = 23009314361/(1x281)

LCM = 23009314361/281

LCM = 81883681

Thus, we can understand that the LCM of 281,281,649,449 is 81883681.
