Find LCM of 576,381,912,297,981 with Prime Factorization
| 2 | 576, 381, 912, 297, 981 |
| 2 | 288, 381, 456, 297, 981 |
| 2 | 144, 381, 228, 297, 981 |
| 2 | 72, 381, 114, 297, 981 |
| 3 | 36, 381, 57, 297, 981 |
| 3 | 12, 127, 19, 99, 327 |
| 4, 127, 19, 33, 109 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 3 x 4 x 127 x 19 x 33 x 109 = 4999427136
Therefore, the lowest common multiple of 576,381,912,297,981 is 4999427136.
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.
576 x 381 x 912 x 297 x 981 = 58313318114304
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.
576 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 64, 72, 96, 144, 192, 288, 576
381 : 1, 3, 127, 381
912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912
297 : 1, 3, 9, 11, 27, 33, 99, 297
981 : 1, 3, 9, 109, 327, 981
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 576,381,912,297,981, is 3.
Now, the common factors can be found like this.
576:2x 2x 2x 2x 2x 2x 3x 3
381:3x 127
912:2x 2x 2x 2x 3x 19
297:3x 3x 3x 11
981:3x 3x 109
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 3x 3x 3x 3 = 3888
Therefore, the value for common factors is 3888.
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 = 58313318114304/(3x3888)
LCM = 58313318114304/11664
LCM = 4999427136
Thus, we can understand that the LCM of 576,381,912,297,981 is 4999427136.
