Given numbers are 673,391,257,690,397

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

The LCM of 673,391,257,690,397 is 805446514410.

Find LCM of 673,391,257,690,397 with Prime Factorization

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

23 x 673 x 17 x 257 x 30 x 397 = 805446514410

Therefore, the lowest common multiple of 673,391,257,690,397 is 805446514410.

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.

673 x 391 x 257 x 690 x 397 = 18525269831430

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.

673 : 1, 673

391 : 1, 17, 23, 391

257 : 1, 257

690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690

397 : 1, 397

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 673,391,257,690,397, is 1.

Now, the common factors can be found like this.

673:673

391:17x 23

257:257

690:2x 3x 5x 23

397:397

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

23 = 23

Therefore, the value for common factors is 23.

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 = 18525269831430/(1x23)

LCM = 18525269831430/23

LCM = 805446514410

Thus, we can understand that the LCM of 673,391,257,690,397 is 805446514410.
