The LCM of 816,124,292,992 is 3693216.
Find LCM of 816,124,292,992 with Prime Factorization
| 2 | 816, 124, 292, 992 |
| 2 | 408, 62, 146, 496 |
| 2 | 204, 31, 73, 248 |
| 2 | 102, 31, 73, 124 |
| 31 | 51, 31, 73, 62 |
| 51, 1, 73, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 31 x 51 x 1 x 73 x 2 = 3693216
Therefore, the lowest common multiple of 816,124,292,992 is 3693216.
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 124 x 292 x 992 = 29309362176
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
124 : 1, 2, 4, 31, 62, 124
292 : 1, 2, 4, 73, 146, 292
992 : 1, 2, 4, 8, 16, 31, 32, 62, 124, 248, 496, 992
4 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 816,124,292,992, is 4.
Now, the common factors can be found like this.
816:2x 2x 2x 2x 3x 17
124:2x 2x 31
292:2x 2x 73
992:2x 2x 2x 2x 2x 31
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 31 = 1984
Therefore, the value for common factors is 1984.
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 = 29309362176/(4x1984)
LCM = 29309362176/7936
LCM = 3693216
Thus, we can understand that the LCM of 816,124,292,992 is 3693216.
