Given numbers are 945,981,831,264,762
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 945,981,831,264,762 is 318877934760.
Find LCM of 945,981,831,264,762 with Prime Factorization
| 2 | 945, 981, 831, 264, 762 |
| 3 | 945, 981, 831, 132, 381 |
| 3 | 315, 327, 277, 44, 127 |
| 105, 109, 277, 44, 127 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 105 x 109 x 277 x 44 x 127 = 318877934760
Therefore, the lowest common multiple of 945,981,831,264,762 is 318877934760.
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.
945 x 981 x 831 x 264 x 762 = 154974676293360
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.
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
981 : 1, 3, 9, 109, 327, 981
831 : 1, 3, 277, 831
264 : 1, 2, 3, 4, 6, 8, 11, 12, 22, 24, 33, 44, 66, 88, 132, 264
762 : 1, 2, 3, 6, 127, 254, 381, 762
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 945,981,831,264,762, is 3.
Now, the common factors can be found like this.
945:3x 3x 3x 5x 7
981:3x 3x 109
831:3x 277
264:2x 2x 2x 3x 11
762:2x 3x 127
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3x 3 = 162
Therefore, the value for common factors is 162.
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 = 154974676293360/(3x162)
LCM = 154974676293360/486
LCM = 318877934760
Thus, we can understand that the LCM of 945,981,831,264,762 is 318877934760.
