The LCM of 511,192,280,981 is 160413120.
Find LCM of 511,192,280,981 with Prime Factorization
| 2 | 511, 192, 280, 981 |
| 2 | 511, 96, 140, 981 |
| 2 | 511, 48, 70, 981 |
| 3 | 511, 24, 35, 981 |
| 7 | 511, 8, 35, 327 |
| 73, 8, 5, 327 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 7 x 73 x 8 x 5 x 327 = 160413120
Therefore, the lowest common multiple of 511,192,280,981 is 160413120.
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.
511 x 192 x 280 x 981 = 26949404160
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.
511 : 1, 7, 73, 511
192 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 192
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
981 : 1, 3, 9, 109, 327, 981
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 511,192,280,981, is 1.
Now, the common factors can be found like this.
511:7x 73
192:2x 2x 2x 2x 2x 2x 3
280:2x 2x 2x 5x 7
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 3x 7 = 168
Therefore, the value for common factors is 168.
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 = 26949404160/(1x168)
LCM = 26949404160/168
LCM = 160413120
Thus, we can understand that the LCM of 511,192,280,981 is 160413120.
