Given numbers are 397,821,794,857

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

The LCM of 397,821,794,857 is 558656018.

Find LCM of 397,821,794,857 with Prime Factorization

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

397 x 1 x 821 x 2 x 857 = 558656018

Therefore, the lowest common multiple of 397,821,794,857 is 558656018.

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.

397 x 821 x 794 x 857 = 221786439146

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.

397 : 1, 397

821 : 1, 821

794 : 1, 2, 397, 794

857 : 1, 857

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 397,821,794,857, is 1.

Now, the common factors can be found like this.

397:397

821:821

794:2x 397

857:857

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

397 = 397

Therefore, the value for common factors is 397.

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 = 221786439146/(1x397)

LCM = 221786439146/397

LCM = 558656018

Thus, we can understand that the LCM of 397,821,794,857 is 558656018.
