Find LCM of 867,551,999,972,646 with Prime Factorization
| 2 | 867, 551, 999, 972, 646 |
| 3 | 867, 551, 999, 486, 323 |
| 3 | 289, 551, 333, 162, 323 |
| 3 | 289, 551, 111, 54, 323 |
| 17 | 289, 551, 37, 18, 323 |
| 19 | 17, 551, 37, 18, 19 |
| 17, 29, 37, 18, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 17 x 19 x 17 x 29 x 37 x 18 x 1 = 5726871396
Therefore, the lowest common multiple of 867,551,999,972,646 is 5726871396.
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.
867 x 551 x 999 x 972 x 646 = 299664272667096
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.
867 : 1, 3, 17, 51, 289, 867
551 : 1, 19, 29, 551
999 : 1, 3, 9, 27, 37, 111, 333, 999
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
646 : 1, 2, 17, 19, 34, 38, 323, 646
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 867,551,999,972,646, is 1.
Now, the common factors can be found like this.
867:3x 17x 17
551:19x 29
999:3x 3x 3x 37
972:2x 2x 3x 3x 3x 3x 3
646:2x 17x 19
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 3x 17x 19 = 52326
Therefore, the value for common factors is 52326.
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 = 299664272667096/(1x52326)
LCM = 299664272667096/52326
LCM = 5726871396
Thus, we can understand that the LCM of 867,551,999,972,646 is 5726871396.
