Find LCM of 756,990,881,105 with Prime Factorization
| 2 | 756, 990, 881, 105 |
| 3 | 378, 495, 881, 105 |
| 3 | 126, 165, 881, 35 |
| 5 | 42, 55, 881, 35 |
| 7 | 42, 11, 881, 7 |
| 6, 11, 881, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 7 x 6 x 11 x 881 x 1 = 36631980
Therefore, the lowest common multiple of 756,990,881,105 is 36631980.
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 990 x 881 x 105 = 69234442200
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
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
881 : 1, 881
105 : 1, 3, 5, 7, 15, 21, 35, 105
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 756,990,881,105, is 1.
Now, the common factors can be found like this.
756:2x 2x 3x 3x 3x 7
990:2x 3x 3x 5x 11
881:881
105:3x 5x 7
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 3x 5x 7 = 1890
Therefore, the value for common factors is 1890.
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 = 69234442200/(1x1890)
LCM = 69234442200/1890
LCM = 36631980
Thus, we can understand that the LCM of 756,990,881,105 is 36631980.
