Given numbers are 897,115,391,939

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

The LCM of 897,115,391,939 is 23864685.

Find LCM of 897,115,391,939 with Prime Factorization

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

3 x 23 x 13 x 5 x 17 x 313 = 23864685

Therefore, the lowest common multiple of 897,115,391,939 is 23864685.

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.

897 x 115 x 391 x 939 = 37873255095

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.

897 : 1, 3, 13, 23, 39, 69, 299, 897

115 : 1, 5, 23, 115

391 : 1, 17, 23, 391

939 : 1, 3, 313, 939

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 897,115,391,939, is 1.

Now, the common factors can be found like this.

897:3x 13x 23

115:5x 23

391:17x 23

939:3x 313

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

3x 23x 23 = 1587

Therefore, the value for common factors is 1587.

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 = 37873255095/(1x1587)

LCM = 37873255095/1587

LCM = 23864685

Thus, we can understand that the LCM of 897,115,391,939 is 23864685.
