The LCM of 832,434,819,391 is 635334336.
Find LCM of 832,434,819,391 with Prime Factorization
| 2 | 832, 434, 819, 391 |
| 7 | 416, 217, 819, 391 |
| 13 | 416, 31, 117, 391 |
| 32, 31, 9, 391 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 13 x 32 x 31 x 9 x 391 = 635334336
Therefore, the lowest common multiple of 832,434,819,391 is 635334336.
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.
832 x 434 x 819 x 391 = 115630849152
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.
832 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 64, 104, 208, 416, 832
434 : 1, 2, 7, 14, 31, 62, 217, 434
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
391 : 1, 17, 23, 391
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 832,434,819,391, is 1.
Now, the common factors can be found like this.
832:2x 2x 2x 2x 2x 2x 13
434:2x 7x 31
819:3x 3x 7x 13
391:17x 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 7x 13 = 182
Therefore, the value for common factors is 182.
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 = 115630849152/(1x182)
LCM = 115630849152/182
LCM = 635334336
Thus, we can understand that the LCM of 832,434,819,391 is 635334336.
