Find LCM of 128,721,806,546,552 with Prime Factorization
| 2 | 128, 721, 806, 546, 552 |
| 2 | 64, 721, 403, 273, 276 |
| 2 | 32, 721, 403, 273, 138 |
| 3 | 16, 721, 403, 273, 69 |
| 7 | 16, 721, 403, 91, 23 |
| 13 | 16, 103, 403, 13, 23 |
| 16, 103, 31, 1, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 7 x 13 x 16 x 103 x 31 x 1 x 23 = 2566252416
Therefore, the lowest common multiple of 128,721,806,546,552 is 2566252416.
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.
128 x 721 x 806 x 546 x 552 = 22418781106176
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.
128 : 1, 2, 4, 8, 16, 32, 64, 128
721 : 1, 7, 103, 721
806 : 1, 2, 13, 26, 31, 62, 403, 806
546 : 1, 2, 3, 6, 7, 13, 14, 21, 26, 39, 42, 78, 91, 182, 273, 546
552 : 1, 2, 3, 4, 6, 8, 12, 23, 24, 46, 69, 92, 138, 184, 276, 552
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 128,721,806,546,552, is 1.
Now, the common factors can be found like this.
128:2x 2x 2x 2x 2x 2x 2
721:7x 103
806:2x 13x 31
546:2x 3x 7x 13
552:2x 2x 2x 3x 23
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 2x 2x 3x 7x 13 = 8736
Therefore, the value for common factors is 8736.
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 = 22418781106176/(1x8736)
LCM = 22418781106176/8736
LCM = 2566252416
Thus, we can understand that the LCM of 128,721,806,546,552 is 2566252416.
