Given numbers are 455,845,715,242,818
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 455,845,715,242,818 is 585454870.
Find LCM of 455,845,715,242,818 with Prime Factorization
| 2 | 455, 845, 715, 242, 818 |
| 5 | 455, 845, 715, 121, 409 |
| 11 | 91, 169, 143, 121, 409 |
| 13 | 91, 169, 13, 11, 409 |
| 7, 1, 13, 11, 409 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 11 x 13 x 7 x 1 x 13 x 11 x 409 = 585454870
Therefore, the lowest common multiple of 455,845,715,242,818 is 585454870.
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.
455 x 845 x 715 x 242 x 818 = 54418030166500
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.
455 : 1, 5, 7, 13, 35, 65, 91, 455
845 : 1, 5, 13, 65, 169, 845
715 : 1, 5, 11, 13, 55, 65, 143, 715
242 : 1, 2, 11, 22, 121, 242
818 : 1, 2, 409, 818
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 455,845,715,242,818, is 1.
Now, the common factors can be found like this.
455:5x 7x 13
845:5x 13x 13
715:5x 11x 13
242:2x 11x 11
818:2x 409
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 5x 11x 13x 13 = 92950
Therefore, the value for common factors is 92950.
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 = 54418030166500/(1x92950)
LCM = 54418030166500/92950
LCM = 585454870
Thus, we can understand that the LCM of 455,845,715,242,818 is 585454870.
