Given numbers are 453,644,161,439

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

The LCM of 453,644,161,439 is 128070348.

Find LCM of 453,644,161,439 with Prime Factorization

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

7 x 23 x 453 x 4 x 1 x 439 = 128070348

Therefore, the lowest common multiple of 453,644,161,439 is 128070348.

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.

453 x 644 x 161 x 439 = 20619326028

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.

453 : 1, 3, 151, 453

644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644

161 : 1, 7, 23, 161

439 : 1, 439

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 453,644,161,439, is 1.

Now, the common factors can be found like this.

453:3x 151

644:2x 2x 7x 23

161:7x 23

439:439

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

7x 23 = 161

Therefore, the value for common factors is 161.

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 = 20619326028/(1x161)

LCM = 20619326028/161

LCM = 128070348

Thus, we can understand that the LCM of 453,644,161,439 is 128070348.
