Given numbers are 330,628,981,867,812
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 330,628,981,867,812 is 1987857374580.
Find LCM of 330,628,981,867,812 with Prime Factorization
| 2 | 330, 628, 981, 867, 812 |
| 2 | 165, 314, 981, 867, 406 |
| 3 | 165, 157, 981, 867, 203 |
| 55, 157, 327, 289, 203 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 55 x 157 x 327 x 289 x 203 = 1987857374580
Therefore, the lowest common multiple of 330,628,981,867,812 is 1987857374580.
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.
330 x 628 x 981 x 867 x 812 = 143125730969760
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.
330 : 1, 2, 3, 5, 6, 10, 11, 15, 22, 30, 33, 55, 66, 110, 165, 330
628 : 1, 2, 4, 157, 314, 628
981 : 1, 3, 9, 109, 327, 981
867 : 1, 3, 17, 51, 289, 867
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 330,628,981,867,812, is 1.
Now, the common factors can be found like this.
330:2x 3x 5x 11
628:2x 2x 157
981:3x 3x 109
867:3x 17x 17
812:2x 2x 7x 29
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 3 = 72
Therefore, the value for common factors is 72.
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 = 143125730969760/(1x72)
LCM = 143125730969760/72
LCM = 1987857374580
Thus, we can understand that the LCM of 330,628,981,867,812 is 1987857374580.
