Given numbers are 896,392,644,648
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 896,392,644,648 is 11684736.
Find LCM of 896,392,644,648 with Prime Factorization
| 2 | 896, 392, 644, 648 |
| 2 | 448, 196, 322, 324 |
| 2 | 224, 98, 161, 162 |
| 7 | 112, 49, 161, 81 |
| 16, 7, 23, 81 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 7 x 16 x 7 x 23 x 81 = 11684736
Therefore, the lowest common multiple of 896,392,644,648 is 11684736.
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.
896 x 392 x 644 x 648 = 146573328384
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.
896 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 128, 224, 448, 896
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648
4 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 896,392,644,648, is 4.
Now, the common factors can be found like this.
896:2x 2x 2x 2x 2x 2x 2x 7
392:2x 2x 2x 7x 7
644:2x 2x 7x 23
648:2x 2x 2x 3x 3x 3x 3
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 2x 7x 7 = 3136
Therefore, the value for common factors is 3136.
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 = 146573328384/(4x3136)
LCM = 146573328384/12544
LCM = 11684736
Thus, we can understand that the LCM of 896,392,644,648 is 11684736.
