The LCM of 821,981,805,225,230 is 6483478050.
Find LCM of 821,981,805,225,230 with Prime Factorization
| 3 | 821, 981, 805, 225, 230 |
| 3 | 821, 327, 805, 75, 230 |
| 5 | 821, 109, 805, 25, 230 |
| 23 | 821, 109, 161, 5, 46 |
| 821, 109, 7, 5, 2 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 23 x 821 x 109 x 7 x 5 x 2 = 6483478050
Therefore, the lowest common multiple of 821,981,805,225,230 is 6483478050.
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.
821 x 981 x 805 x 225 x 230 = 33551998908750
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.
821 : 1, 821
981 : 1, 3, 9, 109, 327, 981
805 : 1, 5, 7, 23, 35, 115, 161, 805
225 : 1, 3, 5, 9, 15, 25, 45, 75, 225
230 : 1, 2, 5, 10, 23, 46, 115, 230
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,981,805,225,230, is 1.
Now, the common factors can be found like this.
821:821
981:3x 3x 109
805:5x 7x 23
225:3x 3x 5x 5
230:2x 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.
3x 3x 5x 5x 23 = 5175
Therefore, the value for common factors is 5175.
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 = 33551998908750/(1x5175)
LCM = 33551998908750/5175
LCM = 6483478050
Thus, we can understand that the LCM of 821,981,805,225,230 is 6483478050.
