Given numbers are 231,762,578,889
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 231,762,578,889 is 16956786.
Find LCM of 231,762,578,889 with Prime Factorization
| 2 | 231, 762, 578, 889 |
| 3 | 231, 381, 289, 889 |
| 7 | 77, 127, 289, 889 |
| 127 | 11, 127, 289, 127 |
| 11, 1, 289, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 127 x 11 x 1 x 289 x 1 = 16956786
Therefore, the lowest common multiple of 231,762,578,889 is 16956786.
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.
231 x 762 x 578 x 889 = 90447496524
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.
231 : 1, 3, 7, 11, 21, 33, 77, 231
762 : 1, 2, 3, 6, 127, 254, 381, 762
578 : 1, 2, 17, 34, 289, 578
889 : 1, 7, 127, 889
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 231,762,578,889, is 1.
Now, the common factors can be found like this.
231:3x 7x 11
762:2x 3x 127
578:2x 17x 17
889:7x 127
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 7x 127 = 5334
Therefore, the value for common factors is 5334.
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 = 90447496524/(1x5334)
LCM = 90447496524/5334
LCM = 16956786
Thus, we can understand that the LCM of 231,762,578,889 is 16956786.
