Find LCM of 328,715,385,677,856 with Prime Factorization
| 2 | 328, 715, 385, 677, 856 |
| 2 | 164, 715, 385, 677, 428 |
| 2 | 82, 715, 385, 677, 214 |
| 5 | 41, 715, 385, 677, 107 |
| 11 | 41, 143, 77, 677, 107 |
| 41, 13, 7, 677, 107 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 11 x 41 x 13 x 7 x 677 x 107 = 118918759960
Therefore, the lowest common multiple of 328,715,385,677,856 is 118918759960.
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.
328 x 715 x 385 x 677 x 856 = 52324254382400
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.
328 : 1, 2, 4, 8, 41, 82, 164, 328
715 : 1, 5, 11, 13, 55, 65, 143, 715
385 : 1, 5, 7, 11, 35, 55, 77, 385
677 : 1, 677
856 : 1, 2, 4, 8, 107, 214, 428, 856
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 328,715,385,677,856, is 1.
Now, the common factors can be found like this.
328:2x 2x 2x 41
715:5x 11x 13
385:5x 7x 11
677:677
856:2x 2x 2x 107
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 5x 11 = 440
Therefore, the value for common factors is 440.
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 = 52324254382400/(1x440)
LCM = 52324254382400/440
LCM = 118918759960
Thus, we can understand that the LCM of 328,715,385,677,856 is 118918759960.
