Given numbers are 423,251,187,240,491

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

The LCM of 423,251,187,240,491 is 779878907280.

Find LCM of 423,251,187,240,491 with Prime Factorization

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

3 x 141 x 251 x 187 x 80 x 491 = 779878907280

Therefore, the lowest common multiple of 423,251,187,240,491 is 779878907280.

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.

423 x 251 x 187 x 240 x 491 = 2339636721840

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.

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

251 : 1, 251

187 : 1, 11, 17, 187

240 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240

491 : 1, 491

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 423,251,187,240,491, is 1.

Now, the common factors can be found like this.

423:3x 3x 47

251:251

187:11x 17

240:2x 2x 2x 2x 3x 5

491:491

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 = 2339636721840/(1x3)

LCM = 2339636721840/3

LCM = 779878907280

Thus, we can understand that the LCM of 423,251,187,240,491 is 779878907280.
