Given numbers are 447,351,771,257

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

The LCM of 447,351,771,257 is 13440843.

Find LCM of 447,351,771,257 with Prime Factorization

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

3 x 257 x 149 x 117 x 1 x 1 = 13440843

Therefore, the lowest common multiple of 447,351,771,257 is 13440843.

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.

447 x 351 x 771 x 257 = 31088669859

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.

447 : 1, 3, 149, 447

351 : 1, 3, 9, 13, 27, 39, 117, 351

771 : 1, 3, 257, 771

257 : 1, 257

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 447,351,771,257, is 1.

Now, the common factors can be found like this.

447:3x 149

351:3x 3x 3x 13

771:3x 257

257:257

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

3x 3x 257 = 2313

Therefore, the value for common factors is 2313.

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 = 31088669859/(1x2313)

LCM = 31088669859/2313

LCM = 13440843

Thus, we can understand that the LCM of 447,351,771,257 is 13440843.
