Given numbers are 687,505,702,127,858
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 687,505,702,127,858 is 113412357630.
Find LCM of 687,505,702,127,858 with Prime Factorization
| 2 | 687, 505, 702, 127, 858 |
| 3 | 687, 505, 351, 127, 429 |
| 13 | 229, 505, 117, 127, 143 |
| 229, 505, 9, 127, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 229 x 505 x 9 x 127 x 11 = 113412357630
Therefore, the lowest common multiple of 687,505,702,127,858 is 113412357630.
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.
687 x 505 x 702 x 127 x 858 = 26538491685420
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.
687 : 1, 3, 229, 687
505 : 1, 5, 101, 505
702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702
127 : 1, 127
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 687,505,702,127,858, is 1.
Now, the common factors can be found like this.
687:3x 229
505:5x 101
702:2x 3x 3x 3x 13
127:127
858:2x 3x 11x 13
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 3x 13 = 234
Therefore, the value for common factors is 234.
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 = 26538491685420/(1x234)
LCM = 26538491685420/234
LCM = 113412357630
Thus, we can understand that the LCM of 687,505,702,127,858 is 113412357630.
