The LCM of 793,180,676,828 is 42679260.
Find LCM of 793,180,676,828 with Prime Factorization
| 2 | 793, 180, 676, 828 |
| 2 | 793, 90, 338, 414 |
| 3 | 793, 45, 169, 207 |
| 3 | 793, 15, 169, 69 |
| 13 | 793, 5, 169, 23 |
| 61, 5, 13, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 13 x 61 x 5 x 13 x 23 = 42679260
Therefore, the lowest common multiple of 793,180,676,828 is 42679260.
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.
793 x 180 x 676 x 828 = 79895574720
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.
793 : 1, 13, 61, 793
180 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180
676 : 1, 2, 4, 13, 26, 52, 169, 338, 676
828 : 1, 2, 3, 4, 6, 9, 12, 18, 23, 36, 46, 69, 92, 138, 207, 276, 414, 828
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 793,180,676,828, is 1.
Now, the common factors can be found like this.
793:13x 61
180:2x 2x 3x 3x 5
676:2x 2x 13x 13
828:2x 2x 3x 3x 23
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 3x 13 = 1872
Therefore, the value for common factors is 1872.
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 = 79895574720/(1x1872)
LCM = 79895574720/1872
LCM = 42679260
Thus, we can understand that the LCM of 793,180,676,828 is 42679260.
