Given numbers are 391,411,685,431

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

The LCM of 391,411,685,431 is 346310655.

Find LCM of 391,411,685,431 with Prime Factorization

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

137 x 391 x 3 x 5 x 431 = 346310655

Therefore, the lowest common multiple of 391,411,685,431 is 346310655.

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.

391 x 411 x 685 x 431 = 47444559735

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.

391 : 1, 17, 23, 391

411 : 1, 3, 137, 411

685 : 1, 5, 137, 685

431 : 1, 431

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,411,685,431, is 1.

Now, the common factors can be found like this.

391:17x 23

411:3x 137

685:5x 137

431:431

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

137 = 137

Therefore, the value for common factors is 137.

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 = 47444559735/(1x137)

LCM = 47444559735/137

LCM = 346310655

Thus, we can understand that the LCM of 391,411,685,431 is 346310655.
