Given numbers are 423,418,247,391

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

The LCM of 423,418,247,391 is 898745562.

Find LCM of 423,418,247,391 with Prime Factorization

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

19 x 423 x 22 x 13 x 391 = 898745562

Therefore, the lowest common multiple of 423,418,247,391 is 898745562.

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 418 x 247 x 391 = 17076165678

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

418 : 1, 2, 11, 19, 22, 38, 209, 418

247 : 1, 13, 19, 247

391 : 1, 17, 23, 391

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 423,418,247,391, is 1.

Now, the common factors can be found like this.

423:3x 3x 47

418:2x 11x 19

247:13x 19

391:17x 23

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

19 = 19

Therefore, the value for common factors is 19.

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 = 17076165678/(1x19)

LCM = 17076165678/19

LCM = 898745562

Thus, we can understand that the LCM of 423,418,247,391 is 898745562.
