The LCM of 290,629,728,884 is 66397240.
Find LCM of 290,629,728,884 with Prime Factorization
| 2 | 290, 629, 728, 884 |
| 2 | 145, 629, 364, 442 |
| 13 | 145, 629, 182, 221 |
| 17 | 145, 629, 14, 17 |
| 145, 37, 14, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 13 x 17 x 145 x 37 x 14 x 1 = 66397240
Therefore, the lowest common multiple of 290,629,728,884 is 66397240.
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.
290 x 629 x 728 x 884 = 117390320320
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.
290 : 1, 2, 5, 10, 29, 58, 145, 290
629 : 1, 17, 37, 629
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
884 : 1, 2, 4, 13, 17, 26, 34, 52, 68, 221, 442, 884
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 290,629,728,884, is 1.
Now, the common factors can be found like this.
290:2x 5x 29
629:17x 37
728:2x 2x 2x 7x 13
884:2x 2x 13x 17
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 13x 17 = 1768
Therefore, the value for common factors is 1768.
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 = 117390320320/(1x1768)
LCM = 117390320320/1768
LCM = 66397240
Thus, we can understand that the LCM of 290,629,728,884 is 66397240.
