Given numbers are 317,681,390,258

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

The LCM of 317,681,390,258 is 1206752430.

Find LCM of 317,681,390,258 with Prime Factorization

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

2 x 3 x 317 x 227 x 65 x 43 = 1206752430

Therefore, the lowest common multiple of 317,681,390,258 is 1206752430.

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.

317 x 681 x 390 x 258 = 21721543740

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.

317 : 1, 317

681 : 1, 3, 227, 681

390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390

258 : 1, 2, 3, 6, 43, 86, 129, 258

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 317,681,390,258, is 1.

Now, the common factors can be found like this.

317:317

681:3x 227

390:2x 3x 5x 13

258:2x 3x 43

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

2x 3x 3 = 18

Therefore, the value for common factors is 18.

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 = 21721543740/(1x18)

LCM = 21721543740/18

LCM = 1206752430

Thus, we can understand that the LCM of 317,681,390,258 is 1206752430.
