Find LCM of 684,221,361,111,918 with Prime Factorization
| 2 | 684, 221, 361, 111, 918 |
| 3 | 342, 221, 361, 111, 459 |
| 3 | 114, 221, 361, 37, 153 |
| 17 | 38, 221, 361, 37, 51 |
| 19 | 38, 13, 361, 37, 3 |
| 2, 13, 19, 37, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 17 x 19 x 2 x 13 x 19 x 37 x 3 = 318804876
Therefore, the lowest common multiple of 684,221,361,111,918 is 318804876.
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.
684 x 221 x 361 x 111 x 918 = 5560594647192
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.
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
221 : 1, 13, 17, 221
361 : 1, 19, 361
111 : 1, 3, 37, 111
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 684,221,361,111,918, is 1.
Now, the common factors can be found like this.
684:2x 2x 3x 3x 19
221:13x 17
361:19x 19
111:3x 37
918:2x 3x 3x 3x 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 3x 3x 3x 17x 19 = 17442
Therefore, the value for common factors is 17442.
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 = 5560594647192/(1x17442)
LCM = 5560594647192/17442
LCM = 318804876
Thus, we can understand that the LCM of 684,221,361,111,918 is 318804876.
