Given numbers are 417,621,284,423

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

The LCM of 417,621,284,423 is 1152186012.

Find LCM of 417,621,284,423 with Prime Factorization

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

3 x 3 x 139 x 69 x 284 x 47 = 1152186012

Therefore, the lowest common multiple of 417,621,284,423 is 1152186012.

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.

417 x 621 x 284 x 423 = 31109022324

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.

417 : 1, 3, 139, 417

621 : 1, 3, 9, 23, 27, 69, 207, 621

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

423 : 1, 3, 9, 47, 141, 423

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 417,621,284,423, is 1.

Now, the common factors can be found like this.

417:3x 139

621:3x 3x 3x 23

284:2x 2x 71

423:3x 3x 47

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

3x 3x 3 = 27

Therefore, the value for common factors is 27.

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 = 31109022324/(1x27)

LCM = 31109022324/27

LCM = 1152186012

Thus, we can understand that the LCM of 417,621,284,423 is 1152186012.
