Given numbers are 816,840,851,114
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 816,840,851,114 is 461786640.
Find LCM of 816,840,851,114 with Prime Factorization
| 2 | 816, 840, 851, 114 |
| 2 | 408, 420, 851, 57 |
| 2 | 204, 210, 851, 57 |
| 3 | 102, 105, 851, 57 |
| 34, 35, 851, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 34 x 35 x 851 x 19 = 461786640
Therefore, the lowest common multiple of 816,840,851,114 is 461786640.
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.
816 x 840 x 851 x 114 = 66497276160
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.
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
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
851 : 1, 23, 37, 851
114 : 1, 2, 3, 6, 19, 38, 57, 114
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 816,840,851,114, is 1.
Now, the common factors can be found like this.
816:2x 2x 2x 2x 3x 17
840:2x 2x 2x 3x 5x 7
851:23x 37
114:2x 3x 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 2x 2x 2x 3x 3 = 144
Therefore, the value for common factors is 144.
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 = 66497276160/(1x144)
LCM = 66497276160/144
LCM = 461786640
Thus, we can understand that the LCM of 816,840,851,114 is 461786640.
