The LCM of 338,168,780,826 is 8375640.
Find LCM of 338,168,780,826 with Prime Factorization
| 2 | 338, 168, 780, 826 |
| 2 | 169, 84, 390, 413 |
| 3 | 169, 42, 195, 413 |
| 7 | 169, 14, 65, 413 |
| 13 | 169, 2, 65, 59 |
| 13, 2, 5, 59 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 13 x 13 x 2 x 5 x 59 = 8375640
Therefore, the lowest common multiple of 338,168,780,826 is 8375640.
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.
338 x 168 x 780 x 826 = 36584795520
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.
338 : 1, 2, 13, 26, 169, 338
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
826 : 1, 2, 7, 14, 59, 118, 413, 826
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 338,168,780,826, is 2.
Now, the common factors can be found like this.
338:2x 13x 13
168:2x 2x 2x 3x 7
780:2x 2x 3x 5x 13
826:2x 7x 59
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 3x 7x 13 = 2184
Therefore, the value for common factors is 2184.
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 = 36584795520/(2x2184)
LCM = 36584795520/4368
LCM = 8375640
Thus, we can understand that the LCM of 338,168,780,826 is 8375640.
