Given numbers are 126,342,858,682
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 126,342,858,682 is 10612602.
Find LCM of 126,342,858,682 with Prime Factorization
| 2 | 126, 342, 858, 682 |
| 3 | 63, 171, 429, 341 |
| 3 | 21, 57, 143, 341 |
| 11 | 7, 19, 143, 341 |
| 7, 19, 13, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 11 x 7 x 19 x 13 x 31 = 10612602
Therefore, the lowest common multiple of 126,342,858,682 is 10612602.
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.
126 x 342 x 858 x 682 = 25215542352
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.
126 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126
342 : 1, 2, 3, 6, 9, 18, 19, 38, 57, 114, 171, 342
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
682 : 1, 2, 11, 22, 31, 62, 341, 682
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 126,342,858,682, is 2.
Now, the common factors can be found like this.
126:2x 3x 3x 7
342:2x 3x 3x 19
858:2x 3x 11x 13
682:2x 11x 31
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 3x 11 = 1188
Therefore, the value for common factors is 1188.
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 = 25215542352/(2x1188)
LCM = 25215542352/2376
LCM = 10612602
Thus, we can understand that the LCM of 126,342,858,682 is 10612602.
