Find LCM of 909,819,196,194,990 with Prime Factorization
| 2 | 909, 819, 196, 194, 990 |
| 3 | 909, 819, 98, 97, 495 |
| 3 | 303, 273, 98, 97, 165 |
| 7 | 101, 91, 98, 97, 55 |
| 101, 13, 14, 97, 55 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 7 x 101 x 13 x 14 x 97 x 55 = 12356564220
Therefore, the lowest common multiple of 909,819,196,194,990 is 12356564220.
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.
909 x 819 x 196 x 194 x 990 = 28024687650960
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.
909 : 1, 3, 9, 101, 303, 909
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
196 : 1, 2, 4, 7, 14, 28, 49, 98, 196
194 : 1, 2, 97, 194
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 909,819,196,194,990, is 1.
Now, the common factors can be found like this.
909:3x 3x 101
819:3x 3x 7x 13
196:2x 2x 7x 7
194:2x 97
990:2x 3x 3x 5x 11
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 3x 3x 3x 3x 7 = 2268
Therefore, the value for common factors is 2268.
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 = 28024687650960/(1x2268)
LCM = 28024687650960/2268
LCM = 12356564220
Thus, we can understand that the LCM of 909,819,196,194,990 is 12356564220.
