Given numbers are 478,423,209,517

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

The LCM of 478,423,209,517 is 42258546.

Find LCM of 478,423,209,517 with Prime Factorization

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

11 x 47 x 478 x 9 x 19 x 1 = 42258546

Therefore, the lowest common multiple of 478,423,209,517 is 42258546.

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.

478 x 423 x 209 x 517 = 21847668282

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.

478 : 1, 2, 239, 478

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

209 : 1, 11, 19, 209

517 : 1, 11, 47, 517

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 478,423,209,517, is 1.

Now, the common factors can be found like this.

478:2x 239

423:3x 3x 47

209:11x 19

517:11x 47

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

11x 47 = 517

Therefore, the value for common factors is 517.

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 = 21847668282/(1x517)

LCM = 21847668282/517

LCM = 42258546

Thus, we can understand that the LCM of 478,423,209,517 is 42258546.
