Given numbers are 455,447,129,743

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

The LCM of 455,447,129,743 is 6497947365.

Find LCM of 455,447,129,743 with Prime Factorization

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

3 x 455 x 149 x 43 x 743 = 6497947365

Therefore, the lowest common multiple of 455,447,129,743 is 6497947365.

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.

455 x 447 x 129 x 743 = 19493842095

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.

455 : 1, 5, 7, 13, 35, 65, 91, 455

447 : 1, 3, 149, 447

129 : 1, 3, 43, 129

743 : 1, 743

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 455,447,129,743, is 1.

Now, the common factors can be found like this.

455:5x 7x 13

447:3x 149

129:3x 43

743:743

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 = 19493842095/(1x3)

LCM = 19493842095/3

LCM = 6497947365

Thus, we can understand that the LCM of 455,447,129,743 is 6497947365.
