Given numbers are 218,858,921,678,214
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 218,858,921,678,214 is 347147772114.
Find LCM of 218,858,921,678,214 with Prime Factorization
| 2 | 218, 858, 921, 678, 214 |
| 3 | 109, 429, 921, 339, 107 |
| 109, 143, 307, 113, 107 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 109 x 143 x 307 x 113 x 107 = 347147772114
Therefore, the lowest common multiple of 218,858,921,678,214 is 347147772114.
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.
218 x 858 x 921 x 678 x 214 = 24994639592208
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.
218 : 1, 2, 109, 218
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
921 : 1, 3, 307, 921
678 : 1, 2, 3, 6, 113, 226, 339, 678
214 : 1, 2, 107, 214
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 218,858,921,678,214, is 1.
Now, the common factors can be found like this.
218:2x 109
858:2x 3x 11x 13
921:3x 307
678:2x 3x 113
214:2x 107
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 2x 3x 3 = 72
Therefore, the value for common factors is 72.
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 = 24994639592208/(1x72)
LCM = 24994639592208/72
LCM = 347147772114
Thus, we can understand that the LCM of 218,858,921,678,214 is 347147772114.
