Given numbers are 728,328,403,428,719
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 728,328,403,428,719 is 71185181704.
Find LCM of 728,328,403,428,719 with Prime Factorization
| 2 | 728, 328, 403, 428, 719 |
| 2 | 364, 164, 403, 214, 719 |
| 2 | 182, 82, 403, 107, 719 |
| 13 | 91, 41, 403, 107, 719 |
| 7, 41, 31, 107, 719 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 13 x 7 x 41 x 31 x 107 x 719 = 71185181704
Therefore, the lowest common multiple of 728,328,403,428,719 is 71185181704.
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 328 x 403 x 428 x 719 = 29613035588864
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
328 : 1, 2, 4, 8, 41, 82, 164, 328
403 : 1, 13, 31, 403
428 : 1, 2, 4, 107, 214, 428
719 : 1, 719
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 728,328,403,428,719, is 1.
Now, the common factors can be found like this.
728:2x 2x 2x 7x 13
328:2x 2x 2x 41
403:13x 31
428:2x 2x 107
719:719
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 13 = 416
Therefore, the value for common factors is 416.
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 = 29613035588864/(1x416)
LCM = 29613035588864/416
LCM = 71185181704
Thus, we can understand that the LCM of 728,328,403,428,719 is 71185181704.
