Given numbers are 315,815,455,884
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 315,815,455,884 is 45388980.
Find LCM of 315,815,455,884 with Prime Factorization
| 5 | 315, 815, 455, 884 |
| 7 | 63, 163, 91, 884 |
| 13 | 9, 163, 13, 884 |
| 9, 163, 1, 68 |
Multiply the prime numbers at the bottom and the left side.
5 x 7 x 13 x 9 x 163 x 1 x 68 = 45388980
Therefore, the lowest common multiple of 315,815,455,884 is 45388980.
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.
315 x 815 x 455 x 884 = 103259929500
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.
315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315
815 : 1, 5, 163, 815
455 : 1, 5, 7, 13, 35, 65, 91, 455
884 : 1, 2, 4, 13, 17, 26, 34, 52, 68, 221, 442, 884
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 315,815,455,884, is 1.
Now, the common factors can be found like this.
315:3x 3x 5x 7
815:5x 163
455:5x 7x 13
884:2x 2x 13x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 5x 7x 13 = 2275
Therefore, the value for common factors is 2275.
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 = 103259929500/(1x2275)
LCM = 103259929500/2275
LCM = 45388980
Thus, we can understand that the LCM of 315,815,455,884 is 45388980.
