Find LCM of 897,276,442,687 with Prime Factorization
| 2 | 897, 276, 442, 687 |
| 3 | 897, 138, 221, 687 |
| 13 | 299, 46, 221, 229 |
| 23 | 23, 46, 17, 229 |
| 1, 2, 17, 229 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 23 x 1 x 2 x 17 x 229 = 13968084
Therefore, the lowest common multiple of 897,276,442,687 is 13968084.
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 276 x 442 x 687 = 75176228088
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
276 : 1, 2, 3, 4, 6, 12, 23, 46, 69, 92, 138, 276
442 : 1, 2, 13, 17, 26, 34, 221, 442
687 : 1, 3, 229, 687
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 897,276,442,687, is 1.
Now, the common factors can be found like this.
897:3x 13x 23
276:2x 2x 3x 23
442:2x 13x 17
687:3x 229
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 13x 23 = 5382
Therefore, the value for common factors is 5382.
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 = 75176228088/(1x5382)
LCM = 75176228088/5382
LCM = 13968084
Thus, we can understand that the LCM of 897,276,442,687 is 13968084.
