Find LCM of 221,884,484,802,905 with Prime Factorization
| 2 | 221, 884, 484, 802, 905 |
| 2 | 221, 442, 242, 401, 905 |
| 13 | 221, 221, 121, 401, 905 |
| 17 | 17, 17, 121, 401, 905 |
| 1, 1, 121, 401, 905 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 13 x 17 x 1 x 1 x 121 x 401 x 905 = 38817770420
Therefore, the lowest common multiple of 221,884,484,802,905 is 38817770420.
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.
221 x 884 x 484 x 802 x 905 = 68629818102560
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.
221 : 1, 13, 17, 221
884 : 1, 2, 4, 13, 17, 26, 34, 52, 68, 221, 442, 884
484 : 1, 2, 4, 11, 22, 44, 121, 242, 484
802 : 1, 2, 401, 802
905 : 1, 5, 181, 905
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 221,884,484,802,905, is 1.
Now, the common factors can be found like this.
221:13x 17
884:2x 2x 13x 17
484:2x 2x 11x 11
802:2x 401
905:5x 181
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 13x 17 = 1768
Therefore, the value for common factors is 1768.
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 = 68629818102560/(1x1768)
LCM = 68629818102560/1768
LCM = 38817770420
Thus, we can understand that the LCM of 221,884,484,802,905 is 38817770420.
