Given numbers are 763,231,687
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 763,231,687 is 5765991.
Find LCM of 763,231,687 with Prime Factorization
| 3 | 763, 231, 687 |
| 7 | 763, 77, 229 |
| 109, 11, 229 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 109 x 11 x 229 = 5765991
Therefore, the lowest common multiple of 763,231,687 is 5765991.
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.
763 x 231 x 687 = 121085811
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.
763 : 1, 7, 109, 763
231 : 1, 3, 7, 11, 21, 33, 77, 231
687 : 1, 3, 229, 687
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 763,231,687, is 1.
Now, the common factors can be found like this.
763:7x 109
231:3x 7x 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.
3x 7 = 21
Therefore, the value for common factors is 21.
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 = 121085811/(1x21)
LCM = 121085811/21
LCM = 5765991
Thus, we can understand that the LCM of 763,231,687 is 5765991.
