Find LCM of 449,505,646,228,153 with Prime Factorization
| 2 | 449, 505, 646, 228, 153 |
| 3 | 449, 505, 323, 114, 153 |
| 17 | 449, 505, 323, 38, 51 |
| 19 | 449, 505, 19, 38, 3 |
| 449, 505, 1, 2, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 17 x 19 x 449 x 505 x 1 x 2 x 3 = 2636590860
Therefore, the lowest common multiple of 449,505,646,228,153 is 2636590860.
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.
449 x 505 x 646 x 228 x 153 = 5109713086680
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.
449 : 1, 449
505 : 1, 5, 101, 505
646 : 1, 2, 17, 19, 34, 38, 323, 646
228 : 1, 2, 3, 4, 6, 12, 19, 38, 57, 76, 114, 228
153 : 1, 3, 9, 17, 51, 153
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 449,505,646,228,153, is 1.
Now, the common factors can be found like this.
449:449
505:5x 101
646:2x 17x 19
228:2x 2x 3x 19
153:3x 3x 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 3x 17x 19 = 1938
Therefore, the value for common factors is 1938.
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 = 5109713086680/(1x1938)
LCM = 5109713086680/1938
LCM = 2636590860
Thus, we can understand that the LCM of 449,505,646,228,153 is 2636590860.
