The LCM of 831,753,112,240 is 116805360.
Find LCM of 831,753,112,240 with Prime Factorization
| 2 | 831, 753, 112, 240 |
| 2 | 831, 753, 56, 120 |
| 2 | 831, 753, 28, 60 |
| 2 | 831, 753, 14, 30 |
| 3 | 831, 753, 7, 15 |
| 277, 251, 7, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 277 x 251 x 7 x 5 = 116805360
Therefore, the lowest common multiple of 831,753,112,240 is 116805360.
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 753 x 112 x 240 = 16819971840
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
753 : 1, 3, 251, 753
112 : 1, 2, 4, 7, 8, 14, 16, 28, 56, 112
240 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 831,753,112,240, is 1.
Now, the common factors can be found like this.
831:3x 277
753:3x 251
112:2x 2x 2x 2x 7
240:2x 2x 2x 2x 3x 5
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 = 16819971840/(1x144)
LCM = 16819971840/144
LCM = 116805360
Thus, we can understand that the LCM of 831,753,112,240 is 116805360.
