Find LCM of 218,351,845,837,638 with Prime Factorization
| 2 | 218, 351, 845, 837, 638 |
| 3 | 109, 351, 845, 837, 319 |
| 3 | 109, 117, 845, 279, 319 |
| 3 | 109, 39, 845, 93, 319 |
| 13 | 109, 13, 845, 31, 319 |
| 109, 1, 65, 31, 319 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 13 x 109 x 1 x 65 x 31 x 319 = 49184622630
Therefore, the lowest common multiple of 218,351,845,837,638 is 49184622630.
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.
218 x 351 x 845 x 837 x 638 = 34527605086260
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.
218 : 1, 2, 109, 218
351 : 1, 3, 9, 13, 27, 39, 117, 351
845 : 1, 5, 13, 65, 169, 845
837 : 1, 3, 9, 27, 31, 93, 279, 837
638 : 1, 2, 11, 22, 29, 58, 319, 638
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 218,351,845,837,638, is 1.
Now, the common factors can be found like this.
218:2x 109
351:3x 3x 3x 13
845:5x 13x 13
837:3x 3x 3x 31
638:2x 11x 29
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 3x 3x 13 = 702
Therefore, the value for common factors is 702.
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 = 34527605086260/(1x702)
LCM = 34527605086260/702
LCM = 49184622630
Thus, we can understand that the LCM of 218,351,845,837,638 is 49184622630.
