Find LCM of 102,845,840,756,975 with Prime Factorization
| 2 | 102, 845, 840, 756, 975 |
| 2 | 51, 845, 420, 378, 975 |
| 3 | 51, 845, 210, 189, 975 |
| 5 | 17, 845, 70, 63, 325 |
| 7 | 17, 169, 14, 63, 65 |
| 13 | 17, 169, 2, 9, 65 |
| 17, 13, 2, 9, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 7 x 13 x 17 x 13 x 2 x 9 x 5 = 108599400
Therefore, the lowest common multiple of 102,845,840,756,975 is 108599400.
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.
102 x 845 x 840 x 756 x 975 = 53365745160000
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.
102 : 1, 2, 3, 6, 17, 34, 51, 102
845 : 1, 5, 13, 65, 169, 845
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
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
975 : 1, 3, 5, 13, 15, 25, 39, 65, 75, 195, 325, 975
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 102,845,840,756,975, is 1.
Now, the common factors can be found like this.
102:2x 3x 17
845:5x 13x 13
840:2x 2x 2x 3x 5x 7
756:2x 2x 3x 3x 3x 7
975:3x 5x 5x 13
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 2x 3x 3x 3x 5x 5x 7x 13 = 491400
Therefore, the value for common factors is 491400.
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 = 53365745160000/(1x491400)
LCM = 53365745160000/491400
LCM = 108599400
Thus, we can understand that the LCM of 102,845,840,756,975 is 108599400.
