The LCM of 912,418,979,289 is 258033072.
Find LCM of 912,418,979,289 with Prime Factorization
| 2 | 912, 418, 979, 289 |
| 11 | 456, 209, 979, 289 |
| 19 | 456, 19, 89, 289 |
| 24, 1, 89, 289 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 19 x 24 x 1 x 89 x 289 = 258033072
Therefore, the lowest common multiple of 912,418,979,289 is 258033072.
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.
912 x 418 x 979 x 289 = 107857824096
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.
912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912
418 : 1, 2, 11, 19, 22, 38, 209, 418
979 : 1, 11, 89, 979
289 : 1, 17, 289
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 912,418,979,289, is 1.
Now, the common factors can be found like this.
912:2x 2x 2x 2x 3x 19
418:2x 11x 19
979:11x 89
289:17x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11x 19 = 418
Therefore, the value for common factors is 418.
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 = 107857824096/(1x418)
LCM = 107857824096/418
LCM = 258033072
Thus, we can understand that the LCM of 912,418,979,289 is 258033072.
