Given numbers are 857,215,979,451,911
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 857,215,979,451,911 is 6737584226395.
Find LCM of 857,215,979,451,911 with Prime Factorization
| 11 | 857, 215, 979, 451, 911 |
| 857, 215, 89, 41, 911 |
Multiply the prime numbers at the bottom and the left side.
11 x 857 x 215 x 89 x 41 x 911 = 6737584226395
Therefore, the lowest common multiple of 857,215,979,451,911 is 6737584226395.
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.
857 x 215 x 979 x 451 x 911 = 74113426490345
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.
857 : 1, 857
215 : 1, 5, 43, 215
979 : 1, 11, 89, 979
451 : 1, 11, 41, 451
911 : 1, 911
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 857,215,979,451,911, is 1.
Now, the common factors can be found like this.
857:857
215:5x 43
979:11x 89
451:11x 41
911:911
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11 = 11
Therefore, the value for common factors is 11.
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 = 74113426490345/(1x11)
LCM = 74113426490345/11
LCM = 6737584226395
Thus, we can understand that the LCM of 857,215,979,451,911 is 6737584226395.
