Given numbers are 126,898,561,286
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 126,898,561,286 is 137531394.
Find LCM of 126,898,561,286 with Prime Factorization
| 2 | 126, 898, 561, 286 |
| 3 | 63, 449, 561, 143 |
| 11 | 21, 449, 187, 143 |
| 21, 449, 17, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 21 x 449 x 17 x 13 = 137531394
Therefore, the lowest common multiple of 126,898,561,286 is 137531394.
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 898 x 561 x 286 = 18154144008
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
898 : 1, 2, 449, 898
561 : 1, 3, 11, 17, 33, 51, 187, 561
286 : 1, 2, 11, 13, 22, 26, 143, 286
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 126,898,561,286, is 1.
Now, the common factors can be found like this.
126:2x 3x 3x 7
898:2x 449
561:3x 11x 17
286:2x 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 2x 3x 11 = 132
Therefore, the value for common factors is 132.
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 = 18154144008/(1x132)
LCM = 18154144008/132
LCM = 137531394
Thus, we can understand that the LCM of 126,898,561,286 is 137531394.
