Find LCM of 144,910,989,368,661 with Prime Factorization
| 2 | 144, 910, 989, 368, 661 |
| 2 | 72, 455, 989, 184, 661 |
| 2 | 36, 455, 989, 92, 661 |
| 2 | 18, 455, 989, 46, 661 |
| 23 | 9, 455, 989, 23, 661 |
| 9, 455, 43, 1, 661 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 23 x 9 x 455 x 43 x 1 x 661 = 42832324080
Therefore, the lowest common multiple of 144,910,989,368,661 is 42832324080.
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.
144 x 910 x 989 x 368 x 661 = 31524590522880
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.
144 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72, 144
910 : 1, 2, 5, 7, 10, 13, 14, 26, 35, 65, 70, 91, 130, 182, 455, 910
989 : 1, 23, 43, 989
368 : 1, 2, 4, 8, 16, 23, 46, 92, 184, 368
661 : 1, 661
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 144,910,989,368,661, is 1.
Now, the common factors can be found like this.
144:2x 2x 2x 2x 3x 3
910:2x 5x 7x 13
989:23x 43
368:2x 2x 2x 2x 23
661:661
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 23 = 736
Therefore, the value for common factors is 736.
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 = 31524590522880/(1x736)
LCM = 31524590522880/736
LCM = 42832324080
Thus, we can understand that the LCM of 144,910,989,368,661 is 42832324080.
