Find LCM of 728,729,416,611 with Prime Factorization
| 2 | 728, 729, 416, 611 |
| 2 | 364, 729, 208, 611 |
| 2 | 182, 729, 104, 611 |
| 13 | 91, 729, 52, 611 |
| 7, 729, 4, 47 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 13 x 7 x 729 x 4 x 47 = 99773856
Therefore, the lowest common multiple of 728,729,416,611 is 99773856.
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.
728 x 729 x 416 x 611 = 134894253312
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.
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
729 : 1, 3, 9, 27, 81, 243, 729
416 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 104, 208, 416
611 : 1, 13, 47, 611
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 728,729,416,611, is 1.
Now, the common factors can be found like this.
728:2x 2x 2x 7x 13
729:3x 3x 3x 3x 3x 3
416:2x 2x 2x 2x 2x 13
611:13x 47
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 13 = 1352
Therefore, the value for common factors is 1352.
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 = 134894253312/(1x1352)
LCM = 134894253312/1352
LCM = 99773856
Thus, we can understand that the LCM of 728,729,416,611 is 99773856.
