The LCM of 487,884,221,976 is 105043952.
Find LCM of 487,884,221,976 with Prime Factorization
| 2 | 487, 884, 221, 976 |
| 2 | 487, 442, 221, 488 |
| 13 | 487, 221, 221, 244 |
| 17 | 487, 17, 17, 244 |
| 487, 1, 1, 244 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 13 x 17 x 487 x 1 x 1 x 244 = 105043952
Therefore, the lowest common multiple of 487,884,221,976 is 105043952.
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.
487 x 884 x 221 x 976 = 92858853568
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.
487 : 1, 487
884 : 1, 2, 4, 13, 17, 26, 34, 52, 68, 221, 442, 884
221 : 1, 13, 17, 221
976 : 1, 2, 4, 8, 16, 61, 122, 244, 488, 976
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 487,884,221,976, is 1.
Now, the common factors can be found like this.
487:487
884:2x 2x 13x 17
221:13x 17
976:2x 2x 2x 2x 61
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 13x 17 = 884
Therefore, the value for common factors is 884.
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 = 92858853568/(1x884)
LCM = 92858853568/884
LCM = 105043952
Thus, we can understand that the LCM of 487,884,221,976 is 105043952.
