Given numbers are 331,993,204,172
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 331,993,204,172 is 2903532.
Find LCM of 331,993,204,172 with Prime Factorization
| 2 | 331, 993, 204, 172 |
| 2 | 331, 993, 102, 86 |
| 3 | 331, 993, 51, 43 |
| 331 | 331, 331, 17, 43 |
| 1, 1, 17, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 331 x 1 x 1 x 17 x 43 = 2903532
Therefore, the lowest common multiple of 331,993,204,172 is 2903532.
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.
331 x 993 x 204 x 172 = 11532829104
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.
331 : 1, 331
993 : 1, 3, 331, 993
204 : 1, 2, 3, 4, 6, 12, 17, 34, 51, 68, 102, 204
172 : 1, 2, 4, 43, 86, 172
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 331,993,204,172, is 1.
Now, the common factors can be found like this.
331:331
993:3x 331
204:2x 2x 3x 17
172:2x 2x 43
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 331 = 3972
Therefore, the value for common factors is 3972.
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 = 11532829104/(1x3972)
LCM = 11532829104/3972
LCM = 2903532
Thus, we can understand that the LCM of 331,993,204,172 is 2903532.
