Given numbers are 395,640,489,163

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

The LCM of 395,640,489,163 is 24723840.

Find LCM of 395,640,489,163 with Prime Factorization

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

5 x 163 x 79 x 128 x 3 x 1 = 24723840

Therefore, the lowest common multiple of 395,640,489,163 is 24723840.

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.

395 x 640 x 489 x 163 = 20149929600

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.

395 : 1, 5, 79, 395

640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640

489 : 1, 3, 163, 489

163 : 1, 163

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 395,640,489,163, is 1.

Now, the common factors can be found like this.

395:5x 79

640:2x 2x 2x 2x 2x 2x 2x 5

489:3x 163

163:163

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

5x 163 = 815

Therefore, the value for common factors is 815.

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 = 20149929600/(1x815)

LCM = 20149929600/815

LCM = 24723840

Thus, we can understand that the LCM of 395,640,489,163 is 24723840.
