Given numbers are 284,163,668,840

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

The LCM of 284,163,668,840 is 1623460440.

Find LCM of 284,163,668,840 with Prime Factorization

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

2 x 2 x 71 x 163 x 167 x 210 = 1623460440

Therefore, the lowest common multiple of 284,163,668,840 is 1623460440.

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.

284 x 163 x 668 x 840 = 25975367040

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.

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

163 : 1, 163

668 : 1, 2, 4, 167, 334, 668

840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 284,163,668,840, is 1.

Now, the common factors can be found like this.

284:2x 2x 71

163:163

668:2x 2x 167

840:2x 2x 2x 3x 5x 7

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 = 25975367040/(1x16)

LCM = 25975367040/16

LCM = 1623460440

Thus, we can understand that the LCM of 284,163,668,840 is 1623460440.
