Find LCM of 311,684,247,416 with Prime Factorization
| 2 | 311, 684, 247, 416 |
| 2 | 311, 342, 247, 208 |
| 13 | 311, 171, 247, 104 |
| 19 | 311, 171, 19, 8 |
| 311, 9, 1, 8 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 13 x 19 x 311 x 9 x 1 x 8 = 22123296
Therefore, the lowest common multiple of 311,684,247,416 is 22123296.
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.
311 x 684 x 247 x 416 = 21857816448
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.
311 : 1, 311
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
247 : 1, 13, 19, 247
416 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 104, 208, 416
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 311,684,247,416, is 1.
Now, the common factors can be found like this.
311:311
684:2x 2x 3x 3x 19
247:13x 19
416:2x 2x 2x 2x 2x 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 13x 19 = 988
Therefore, the value for common factors is 988.
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 = 21857816448/(1x988)
LCM = 21857816448/988
LCM = 22123296
Thus, we can understand that the LCM of 311,684,247,416 is 22123296.
