Given numbers are 831,551,888,609
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 831,551,888,609 is 948729432.
Find LCM of 831,551,888,609 with Prime Factorization
| 3 | 831, 551, 888, 609 |
| 29 | 277, 551, 296, 203 |
| 277, 19, 296, 7 |
Multiply the prime numbers at the bottom and the left side.
3 x 29 x 277 x 19 x 296 x 7 = 948729432
Therefore, the lowest common multiple of 831,551,888,609 is 948729432.
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.
831 x 551 x 888 x 609 = 247618381752
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.
831 : 1, 3, 277, 831
551 : 1, 19, 29, 551
888 : 1, 2, 3, 4, 6, 8, 12, 24, 37, 74, 111, 148, 222, 296, 444, 888
609 : 1, 3, 7, 21, 29, 87, 203, 609
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 831,551,888,609, is 1.
Now, the common factors can be found like this.
831:3x 277
551:19x 29
888:2x 2x 2x 3x 37
609:3x 7x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 29 = 261
Therefore, the value for common factors is 261.
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 = 247618381752/(1x261)
LCM = 247618381752/261
LCM = 948729432
Thus, we can understand that the LCM of 831,551,888,609 is 948729432.
