Given numbers are 831,844,646,399,225
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 831,844,646,399,225 is 118933800300.
Find LCM of 831,844,646,399,225 with Prime Factorization
| 2 | 831, 844, 646, 399, 225 |
| 3 | 831, 422, 323, 399, 225 |
| 19 | 277, 422, 323, 133, 75 |
| 277, 422, 17, 7, 75 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 19 x 277 x 422 x 17 x 7 x 75 = 118933800300
Therefore, the lowest common multiple of 831,844,646,399,225 is 118933800300.
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.
831 x 844 x 646 x 399 x 225 = 40675359702600
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.
831 : 1, 3, 277, 831
844 : 1, 2, 4, 211, 422, 844
646 : 1, 2, 17, 19, 34, 38, 323, 646
399 : 1, 3, 7, 19, 21, 57, 133, 399
225 : 1, 3, 5, 9, 15, 25, 45, 75, 225
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 831,844,646,399,225, is 1.
Now, the common factors can be found like this.
831:3x 277
844:2x 2x 211
646:2x 17x 19
399:3x 7x 19
225:3x 3x 5x 5
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 19 = 342
Therefore, the value for common factors is 342.
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 = 40675359702600/(1x342)
LCM = 40675359702600/342
LCM = 118933800300
Thus, we can understand that the LCM of 831,844,646,399,225 is 118933800300.
