Given numbers are 487,321,311,945

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

The LCM of 487,321,311,945 is 15314574555.

Find LCM of 487,321,311,945 with Prime Factorization

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

3 x 487 x 107 x 311 x 315 = 15314574555

Therefore, the lowest common multiple of 487,321,311,945 is 15314574555.

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.

487 x 321 x 311 x 945 = 45943723665

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.

487 : 1, 487

321 : 1, 3, 107, 321

311 : 1, 311

945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 487,321,311,945, is 1.

Now, the common factors can be found like this.

487:487

321:3x 107

311:311

945:3x 3x 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.

3 = 3

Therefore, the value for common factors is 3.

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 = 45943723665/(1x3)

LCM = 45943723665/3

LCM = 15314574555

Thus, we can understand that the LCM of 487,321,311,945 is 15314574555.
