Find LCM of 990,616,361,110,912 with Prime Factorization
| 2 | 990, 616, 361, 110, 912 |
| 2 | 495, 308, 361, 55, 456 |
| 2 | 495, 154, 361, 55, 228 |
| 3 | 495, 77, 361, 55, 114 |
| 5 | 165, 77, 361, 55, 38 |
| 11 | 33, 77, 361, 11, 38 |
| 19 | 3, 7, 361, 1, 38 |
| 3, 7, 19, 1, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 11 x 19 x 3 x 7 x 19 x 1 x 2 = 20013840
Therefore, the lowest common multiple of 990,616,361,110,912 is 20013840.
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.
990 x 616 x 361 x 110 x 912 = 22085672716800
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.
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
616 : 1, 2, 4, 7, 8, 11, 14, 22, 28, 44, 56, 77, 88, 154, 308, 616
361 : 1, 19, 361
110 : 1, 2, 5, 10, 11, 22, 55, 110
912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 990,616,361,110,912, is 1.
Now, the common factors can be found like this.
990:2x 3x 3x 5x 11
616:2x 2x 2x 7x 11
361:19x 19
110:2x 5x 11
912:2x 2x 2x 2x 3x 19
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 2x 2x 2x 3x 5x 11x 11x 19 = 1103520
Therefore, the value for common factors is 1103520.
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 = 22085672716800/(1x1103520)
LCM = 22085672716800/1103520
LCM = 20013840
Thus, we can understand that the LCM of 990,616,361,110,912 is 20013840.
