Find LCM of 756,945,258,738,115 with Prime Factorization
| 2 | 756, 945, 258, 738, 115 |
| 3 | 378, 945, 129, 369, 115 |
| 3 | 126, 315, 43, 123, 115 |
| 3 | 42, 105, 43, 41, 115 |
| 5 | 14, 35, 43, 41, 115 |
| 7 | 14, 7, 43, 41, 23 |
| 2, 1, 43, 41, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 5 x 7 x 2 x 1 x 43 x 41 x 23 = 153275220
Therefore, the lowest common multiple of 756,945,258,738,115 is 153275220.
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.
756 x 945 x 258 x 738 x 115 = 15643268953200
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.
756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
258 : 1, 2, 3, 6, 43, 86, 129, 258
738 : 1, 2, 3, 6, 9, 18, 41, 82, 123, 246, 369, 738
115 : 1, 5, 23, 115
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 756,945,258,738,115, is 1.
Now, the common factors can be found like this.
756:2x 2x 3x 3x 3x 7
945:3x 3x 3x 5x 7
258:2x 3x 43
738:2x 3x 3x 41
115:5x 23
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 3x 3x 3x 3x 3x 5x 7 = 102060
Therefore, the value for common factors is 102060.
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 = 15643268953200/(1x102060)
LCM = 15643268953200/102060
LCM = 153275220
Thus, we can understand that the LCM of 756,945,258,738,115 is 153275220.
