Given numbers are 352,728,726,687
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 352,728,726,687 is 242065824.
Find LCM of 352,728,726,687 with Prime Factorization
| 2 | 352, 728, 726, 687 |
| 2 | 176, 364, 363, 687 |
| 2 | 88, 182, 363, 687 |
| 3 | 44, 91, 363, 687 |
| 11 | 44, 91, 121, 229 |
| 4, 91, 11, 229 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 11 x 4 x 91 x 11 x 229 = 242065824
Therefore, the lowest common multiple of 352,728,726,687 is 242065824.
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.
352 x 728 x 726 x 687 = 127810755072
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.
352 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 88, 176, 352
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
726 : 1, 2, 3, 6, 11, 22, 33, 66, 121, 242, 363, 726
687 : 1, 3, 229, 687
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 352,728,726,687, is 1.
Now, the common factors can be found like this.
352:2x 2x 2x 2x 2x 11
728:2x 2x 2x 7x 13
726:2x 3x 11x 11
687:3x 229
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 3x 11 = 528
Therefore, the value for common factors is 528.
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 = 127810755072/(1x528)
LCM = 127810755072/528
LCM = 242065824
Thus, we can understand that the LCM of 352,728,726,687 is 242065824.
