Given numbers are 139,806,960,676
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 139,806,960,676 is 699092160.
Find LCM of 139,806,960,676 with Prime Factorization
| 2 | 139, 806, 960, 676 |
| 2 | 139, 403, 480, 338 |
| 13 | 139, 403, 240, 169 |
| 139, 31, 240, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 13 x 139 x 31 x 240 x 13 = 699092160
Therefore, the lowest common multiple of 139,806,960,676 is 699092160.
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.
139 x 806 x 960 x 676 = 72705584640
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.
139 : 1, 139
806 : 1, 2, 13, 26, 31, 62, 403, 806
960 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 64, 80, 96, 120, 160, 192, 240, 320, 480, 960
676 : 1, 2, 4, 13, 26, 52, 169, 338, 676
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 139,806,960,676, is 1.
Now, the common factors can be found like this.
139:139
806:2x 13x 31
960:2x 2x 2x 2x 2x 2x 3x 5
676:2x 2x 13x 13
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 13 = 104
Therefore, the value for common factors is 104.
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 = 72705584640/(1x104)
LCM = 72705584640/104
LCM = 699092160
Thus, we can understand that the LCM of 139,806,960,676 is 699092160.
