Given numbers are 876,219,132,687
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 876,219,132,687 is 2206644.
Find LCM of 876,219,132,687 with Prime Factorization
| 2 | 876, 219, 132, 687 |
| 2 | 438, 219, 66, 687 |
| 3 | 219, 219, 33, 687 |
| 73 | 73, 73, 11, 229 |
| 1, 1, 11, 229 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 73 x 1 x 1 x 11 x 229 = 2206644
Therefore, the lowest common multiple of 876,219,132,687 is 2206644.
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.
876 x 219 x 132 x 687 = 17397181296
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.
876 : 1, 2, 3, 4, 6, 12, 73, 146, 219, 292, 438, 876
219 : 1, 3, 73, 219
132 : 1, 2, 3, 4, 6, 11, 12, 22, 33, 44, 66, 132
687 : 1, 3, 229, 687
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 876,219,132,687, is 3.
Now, the common factors can be found like this.
876:2x 2x 3x 73
219:3x 73
132:2x 2x 3x 11
687:3x 229
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 3x 3x 73 = 2628
Therefore, the value for common factors is 2628.
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 = 17397181296/(3x2628)
LCM = 17397181296/7884
LCM = 2206644
Thus, we can understand that the LCM of 876,219,132,687 is 2206644.
