Find LCM of 428,897,289,187,360 with Prime Factorization
| 2 | 428, 897, 289, 187, 360 |
| 2 | 214, 897, 289, 187, 180 |
| 3 | 107, 897, 289, 187, 90 |
| 17 | 107, 299, 289, 187, 30 |
| 107, 299, 17, 11, 30 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 17 x 107 x 299 x 17 x 11 x 30 = 36614068920
Therefore, the lowest common multiple of 428,897,289,187,360 is 36614068920.
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.
428 x 897 x 289 x 187 x 360 = 7469270059680
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.
428 : 1, 2, 4, 107, 214, 428
897 : 1, 3, 13, 23, 39, 69, 299, 897
289 : 1, 17, 289
187 : 1, 11, 17, 187
360 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 18, 20, 24, 30, 36, 40, 45, 60, 72, 90, 120, 180, 360
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 428,897,289,187,360, is 1.
Now, the common factors can be found like this.
428:2x 2x 107
897:3x 13x 23
289:17x 17
187:11x 17
360:2x 2x 2x 3x 3x 5
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 3x 17 = 204
Therefore, the value for common factors is 204.
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 = 7469270059680/(1x204)
LCM = 7469270059680/204
LCM = 36614068920
Thus, we can understand that the LCM of 428,897,289,187,360 is 36614068920.
