Find LCM of 448,858,728,247,845 with Prime Factorization
| 2 | 448, 858, 728, 247, 845 |
| 2 | 224, 429, 364, 247, 845 |
| 2 | 112, 429, 182, 247, 845 |
| 7 | 56, 429, 91, 247, 845 |
| 13 | 8, 429, 13, 247, 845 |
| 8, 33, 1, 19, 65 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 7 x 13 x 8 x 33 x 1 x 19 x 65 = 237357120
Therefore, the lowest common multiple of 448,858,728,247,845 is 237357120.
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.
448 x 858 x 728 x 247 x 845 = 58405042375680
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.
448 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 224, 448
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
247 : 1, 13, 19, 247
845 : 1, 5, 13, 65, 169, 845
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 448,858,728,247,845, is 1.
Now, the common factors can be found like this.
448:2x 2x 2x 2x 2x 2x 7
858:2x 3x 11x 13
728:2x 2x 2x 7x 13
247:13x 19
845:5x 13x 13
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 7x 13x 13x 13 = 246064
Therefore, the value for common factors is 246064.
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 = 58405042375680/(1x246064)
LCM = 58405042375680/246064
LCM = 237357120
Thus, we can understand that the LCM of 448,858,728,247,845 is 237357120.
