Given numbers are 872,840,886,364,161
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 872,840,886,364,161 is 12127762920.
Find LCM of 872,840,886,364,161 with Prime Factorization
| 2 | 872, 840, 886, 364, 161 |
| 2 | 436, 420, 443, 182, 161 |
| 2 | 218, 210, 443, 91, 161 |
| 7 | 109, 105, 443, 91, 161 |
| 109, 15, 443, 13, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 7 x 109 x 15 x 443 x 13 x 23 = 12127762920
Therefore, the lowest common multiple of 872,840,886,364,161 is 12127762920.
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.
872 x 840 x 886 x 364 x 161 = 38032664517120
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.
872 : 1, 2, 4, 8, 109, 218, 436, 872
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
886 : 1, 2, 443, 886
364 : 1, 2, 4, 7, 13, 14, 26, 28, 52, 91, 182, 364
161 : 1, 7, 23, 161
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 872,840,886,364,161, is 1.
Now, the common factors can be found like this.
872:2x 2x 2x 109
840:2x 2x 2x 3x 5x 7
886:2x 443
364:2x 2x 7x 13
161:7x 23
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 2x 2x 2x 2x 7x 7 = 3136
Therefore, the value for common factors is 3136.
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 = 38032664517120/(1x3136)
LCM = 38032664517120/3136
LCM = 12127762920
Thus, we can understand that the LCM of 872,840,886,364,161 is 12127762920.
