Given numbers are 126,903,858,178
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 126,903,858,178 is 68954886.
Find LCM of 126,903,858,178 with Prime Factorization
| 2 | 126, 903, 858, 178 |
| 3 | 63, 903, 429, 89 |
| 7 | 21, 301, 143, 89 |
| 3, 43, 143, 89 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 3 x 43 x 143 x 89 = 68954886
Therefore, the lowest common multiple of 126,903,858,178 is 68954886.
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 903 x 858 x 178 = 17376631272
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
903 : 1, 3, 7, 21, 43, 129, 301, 903
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
178 : 1, 2, 89, 178
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 126,903,858,178, is 1.
Now, the common factors can be found like this.
126:2x 3x 3x 7
903:3x 7x 43
858:2x 3x 11x 13
178:2x 89
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 7 = 252
Therefore, the value for common factors is 252.
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 = 17376631272/(1x252)
LCM = 17376631272/252
LCM = 68954886
Thus, we can understand that the LCM of 126,903,858,178 is 68954886.
