Find LCM of 993,642,225,680,731 with Prime Factorization
| 2 | 993, 642, 225, 680, 731 |
| 3 | 993, 321, 225, 340, 731 |
| 5 | 331, 107, 75, 340, 731 |
| 17 | 331, 107, 15, 68, 731 |
| 331, 107, 15, 4, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 17 x 331 x 107 x 15 x 4 x 43 = 46601688600
Therefore, the lowest common multiple of 993,642,225,680,731 is 46601688600.
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.
993 x 642 x 225 x 680 x 731 = 71300583558000
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.
993 : 1, 3, 331, 993
642 : 1, 2, 3, 6, 107, 214, 321, 642
225 : 1, 3, 5, 9, 15, 25, 45, 75, 225
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
731 : 1, 17, 43, 731
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 993,642,225,680,731, is 1.
Now, the common factors can be found like this.
993:3x 331
642:2x 3x 107
225:3x 3x 5x 5
680:2x 2x 2x 5x 17
731:17x 43
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 5x 17 = 1530
Therefore, the value for common factors is 1530.
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 = 71300583558000/(1x1530)
LCM = 71300583558000/1530
LCM = 46601688600
Thus, we can understand that the LCM of 993,642,225,680,731 is 46601688600.
