Given numbers are 838,706,690,217,863

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

The LCM of 838,706,690,217,863 is 19112097339930.

Find LCM of 838,706,690,217,863 with Prime Factorization

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

2 x 419 x 353 x 345 x 217 x 863 = 19112097339930

Therefore, the lowest common multiple of 838,706,690,217,863 is 19112097339930.

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.

838 x 706 x 690 x 217 x 863 = 76448389359720

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.

838 : 1, 2, 419, 838

706 : 1, 2, 353, 706

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

217 : 1, 7, 31, 217

863 : 1, 863

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 838,706,690,217,863, is 1.

Now, the common factors can be found like this.

838:2x 419

706:2x 353

690:2x 3x 5x 23

217:7x 31

863:863

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 76448389359720/(1x4)

LCM = 76448389359720/4

LCM = 19112097339930

Thus, we can understand that the LCM of 838,706,690,217,863 is 19112097339930.
