Find LCM of 447,813,400,987,992 with Prime Factorization
| 2 | 447, 813, 400, 987, 992 |
| 2 | 447, 813, 200, 987, 496 |
| 2 | 447, 813, 100, 987, 248 |
| 2 | 447, 813, 50, 987, 124 |
| 3 | 447, 813, 25, 987, 62 |
| 149, 271, 25, 329, 62 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 149 x 271 x 25 x 329 x 62 = 988381010400
Therefore, the lowest common multiple of 447,813,400,987,992 is 988381010400.
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.
447 x 813 x 400 x 987 x 992 = 142326865497600
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.
447 : 1, 3, 149, 447
813 : 1, 3, 271, 813
400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400
987 : 1, 3, 7, 21, 47, 141, 329, 987
992 : 1, 2, 4, 8, 16, 31, 32, 62, 124, 248, 496, 992
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 447,813,400,987,992, is 1.
Now, the common factors can be found like this.
447:3x 149
813:3x 271
400:2x 2x 2x 2x 5x 5
987:3x 7x 47
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 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 = 142326865497600/(1x144)
LCM = 142326865497600/144
LCM = 988381010400
Thus, we can understand that the LCM of 447,813,400,987,992 is 988381010400.
