Find LCM of 939,455,746,494,819 with Prime Factorization
| 2 | 939, 455, 746, 494, 819 |
| 3 | 939, 455, 373, 247, 819 |
| 7 | 313, 455, 373, 247, 273 |
| 13 | 313, 65, 373, 247, 39 |
| 313, 5, 373, 19, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 13 x 313 x 5 x 373 x 19 x 3 = 18167311890
Therefore, the lowest common multiple of 939,455,746,494,819 is 18167311890.
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.
939 x 455 x 746 x 494 x 819 = 128951579795220
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.
939 : 1, 3, 313, 939
455 : 1, 5, 7, 13, 35, 65, 91, 455
746 : 1, 2, 373, 746
494 : 1, 2, 13, 19, 26, 38, 247, 494
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 939,455,746,494,819, is 1.
Now, the common factors can be found like this.
939:3x 313
455:5x 7x 13
746:2x 373
494:2x 13x 19
819:3x 3x 7x 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 3x 7x 13x 13 = 7098
Therefore, the value for common factors is 7098.
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 = 128951579795220/(1x7098)
LCM = 128951579795220/7098
LCM = 18167311890
Thus, we can understand that the LCM of 939,455,746,494,819 is 18167311890.
