Given numbers are 214,831,310,438,945
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 214,831,310,438,945 is 126768077730.
Find LCM of 214,831,310,438,945 with Prime Factorization
| 2 | 214, 831, 310, 438, 945 |
| 3 | 107, 831, 155, 219, 945 |
| 5 | 107, 277, 155, 73, 315 |
| 107, 277, 31, 73, 63 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 107 x 277 x 31 x 73 x 63 = 126768077730
Therefore, the lowest common multiple of 214,831,310,438,945 is 126768077730.
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.
214 x 831 x 310 x 438 x 945 = 22818253991400
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.
214 : 1, 2, 107, 214
831 : 1, 3, 277, 831
310 : 1, 2, 5, 10, 31, 62, 155, 310
438 : 1, 2, 3, 6, 73, 146, 219, 438
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 214,831,310,438,945, is 1.
Now, the common factors can be found like this.
214:2x 107
831:3x 277
310:2x 5x 31
438:2x 3x 73
945:3x 3x 3x 5x 7
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 3x 3x 5 = 180
Therefore, the value for common factors is 180.
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 = 22818253991400/(1x180)
LCM = 22818253991400/180
LCM = 126768077730
Thus, we can understand that the LCM of 214,831,310,438,945 is 126768077730.
