Given numbers are 847,845,425,215,981

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

The LCM of 847,845,425,215,981 is 2566235496825.

Find LCM of 847,845,425,215,981 with Prime Factorization

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

5 x 847 x 169 x 85 x 43 x 981 = 2566235496825

Therefore, the lowest common multiple of 847,845,425,215,981 is 2566235496825.

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.

847 x 845 x 425 x 215 x 981 = 64155887420625

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.

847 : 1, 7, 11, 77, 121, 847

845 : 1, 5, 13, 65, 169, 845

425 : 1, 5, 17, 25, 85, 425

215 : 1, 5, 43, 215

981 : 1, 3, 9, 109, 327, 981

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 847,845,425,215,981, is 1.

Now, the common factors can be found like this.

847:7x 11x 11

845:5x 13x 13

425:5x 5x 17

215:5x 43

981:3x 3x 109

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

5x 5 = 25

Therefore, the value for common factors is 25.

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 = 64155887420625/(1x25)

LCM = 64155887420625/25

LCM = 2566235496825

Thus, we can understand that the LCM of 847,845,425,215,981 is 2566235496825.
