Given numbers are 724,976,672,678
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 724,976,672,678 is 838409376.
Find LCM of 724,976,672,678 with Prime Factorization
| 2 | 724, 976, 672, 678 |
| 2 | 362, 488, 336, 339 |
| 2 | 181, 244, 168, 339 |
| 2 | 181, 122, 84, 339 |
| 3 | 181, 61, 42, 339 |
| 181, 61, 14, 113 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 181 x 61 x 14 x 113 = 838409376
Therefore, the lowest common multiple of 724,976,672,678 is 838409376.
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.
724 x 976 x 672 x 678 = 321949200384
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.
724 : 1, 2, 4, 181, 362, 724
976 : 1, 2, 4, 8, 16, 61, 122, 244, 488, 976
672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672
678 : 1, 2, 3, 6, 113, 226, 339, 678
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 724,976,672,678, is 2.
Now, the common factors can be found like this.
724:2x 2x 181
976:2x 2x 2x 2x 61
672:2x 2x 2x 2x 2x 3x 7
678:2x 3x 113
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 3 = 192
Therefore, the value for common factors is 192.
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 = 321949200384/(2x192)
LCM = 321949200384/384
LCM = 838409376
Thus, we can understand that the LCM of 724,976,672,678 is 838409376.
