Given numbers are 381,988,678,141,296
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 381,988,678,141,296 is 147941473992.
Find LCM of 381,988,678,141,296 with Prime Factorization
| 2 | 381, 988, 678, 141, 296 |
| 2 | 381, 494, 339, 141, 148 |
| 3 | 381, 247, 339, 141, 74 |
| 127, 247, 113, 47, 74 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 127 x 247 x 113 x 47 x 74 = 147941473992
Therefore, the lowest common multiple of 381,988,678,141,296 is 147941473992.
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.
381 x 988 x 678 x 141 x 296 = 10651786127424
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.
381 : 1, 3, 127, 381
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
678 : 1, 2, 3, 6, 113, 226, 339, 678
141 : 1, 3, 47, 141
296 : 1, 2, 4, 8, 37, 74, 148, 296
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 381,988,678,141,296, is 1.
Now, the common factors can be found like this.
381:3x 127
988:2x 2x 13x 19
678:2x 3x 113
141:3x 47
296:2x 2x 2x 37
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 3x 3 = 72
Therefore, the value for common factors is 72.
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 = 10651786127424/(1x72)
LCM = 10651786127424/72
LCM = 147941473992
Thus, we can understand that the LCM of 381,988,678,141,296 is 147941473992.
