Given numbers are 664,305,556,171,342

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

The LCM of 664,305,556,171,342 is 4813697880.

Find LCM of 664,305,556,171,342 with Prime Factorization

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

2 x 2 x 3 x 3 x 19 x 166 x 305 x 139 x 1 x 1 = 4813697880

Therefore, the lowest common multiple of 664,305,556,171,342 is 4813697880.

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.

664 x 305 x 556 x 171 x 342 = 6585138699840

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.

664 : 1, 2, 4, 8, 83, 166, 332, 664

305 : 1, 5, 61, 305

556 : 1, 2, 4, 139, 278, 556

171 : 1, 3, 9, 19, 57, 171

342 : 1, 2, 3, 6, 9, 18, 19, 38, 57, 114, 171, 342

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 664,305,556,171,342, is 1.

Now, the common factors can be found like this.

664:2x 2x 2x 83

305:5x 61

556:2x 2x 139

171:3x 3x 19

342:2x 3x 3x 19

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

2x 2x 2x 3x 3x 19 = 1368

Therefore, the value for common factors is 1368.

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 = 6585138699840/(1x1368)

LCM = 6585138699840/1368

LCM = 4813697880

Thus, we can understand that the LCM of 664,305,556,171,342 is 4813697880.
