Given numbers are 897,286,845,715
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 897,286,845,715 is 1282710.
Find LCM of 897,286,845,715 with Prime Factorization
| 5 | 897, 286, 845, 715 |
| 11 | 897, 286, 169, 143 |
| 13 | 897, 26, 169, 13 |
| 69, 2, 1, 13 |
Multiply the prime numbers at the bottom and the left side.
5 x 11 x 13 x 69 x 2 x 1 x 13 = 1282710
Therefore, the lowest common multiple of 897,286,845,715 is 1282710.
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.
897 x 286 x 845 x 715 = 154996262850
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.
897 : 1, 3, 13, 23, 39, 69, 299, 897
286 : 1, 2, 11, 13, 22, 26, 143, 286
845 : 1, 5, 13, 65, 169, 845
715 : 1, 5, 11, 13, 55, 65, 143, 715
13 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 897,286,845,715, is 13.
Now, the common factors can be found like this.
897:3x 13x 23
286:2x 11x 13
845:5x 13x 13
715:5x 11x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 11x 13x 13 = 9295
Therefore, the value for common factors is 9295.
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 = 154996262850/(13x9295)
LCM = 154996262850/120835
LCM = 1282710
Thus, we can understand that the LCM of 897,286,845,715 is 1282710.
