Given numbers are 420,284,173,332,127

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

The LCM of 420,284,173,332,127 is 54379543260.

Find LCM of 420,284,173,332,127 with Prime Factorization

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

2 x 2 x 105 x 71 x 173 x 83 x 127 = 54379543260

Therefore, the lowest common multiple of 420,284,173,332,127 is 54379543260.

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.

420 x 284 x 173 x 332 x 127 = 870072692160

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.

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

284 : 1, 2, 4, 71, 142, 284

173 : 1, 173

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

127 : 1, 127

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 420,284,173,332,127, is 1.

Now, the common factors can be found like this.

420:2x 2x 3x 5x 7

284:2x 2x 71

173:173

332:2x 2x 83

127:127

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 2 = 16

Therefore, the value for common factors is 16.

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 = 870072692160/(1x16)

LCM = 870072692160/16

LCM = 54379543260

Thus, we can understand that the LCM of 420,284,173,332,127 is 54379543260.
