Find LCM of 312,423,391,819,317 with Prime Factorization
| 3 | 312, 423, 391, 819, 317 |
| 3 | 104, 141, 391, 273, 317 |
| 13 | 104, 47, 391, 91, 317 |
| 8, 47, 391, 7, 317 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 13 x 8 x 47 x 391 x 7 x 317 = 38168734968
Therefore, the lowest common multiple of 312,423,391,819,317 is 38168734968.
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.
312 x 423 x 391 x 819 x 317 = 13397225973768
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.
312 : 1, 2, 3, 4, 6, 8, 12, 13, 24, 26, 39, 52, 78, 104, 156, 312
423 : 1, 3, 9, 47, 141, 423
391 : 1, 17, 23, 391
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
317 : 1, 317
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 312,423,391,819,317, is 1.
Now, the common factors can be found like this.
312:2x 2x 2x 3x 13
423:3x 3x 47
391:17x 23
819:3x 3x 7x 13
317:317
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 13 = 351
Therefore, the value for common factors is 351.
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 = 13397225973768/(1x351)
LCM = 13397225973768/351
LCM = 38168734968
Thus, we can understand that the LCM of 312,423,391,819,317 is 38168734968.
