Given numbers are 408,422,211,285
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 408,422,211,285 is 8178360.
Find LCM of 408,422,211,285 with Prime Factorization
| 2 | 408, 422, 211, 285 |
| 3 | 204, 211, 211, 285 |
| 211 | 68, 211, 211, 95 |
| 68, 1, 1, 95 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 211 x 68 x 1 x 1 x 95 = 8178360
Therefore, the lowest common multiple of 408,422,211,285 is 8178360.
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.
408 x 422 x 211 x 285 = 10353803760
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.
408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408
422 : 1, 2, 211, 422
211 : 1, 211
285 : 1, 3, 5, 15, 19, 57, 95, 285
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 408,422,211,285, is 1.
Now, the common factors can be found like this.
408:2x 2x 2x 3x 17
422:2x 211
211:211
285:3x 5x 19
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 211 = 1266
Therefore, the value for common factors is 1266.
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 = 10353803760/(1x1266)
LCM = 10353803760/1266
LCM = 8178360
Thus, we can understand that the LCM of 408,422,211,285 is 8178360.
