Given numbers are 459,438,433,189
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 459,438,433,189 is 203119434.
Find LCM of 459,438,433,189 with Prime Factorization
| 3 | 459, 438, 433, 189 |
| 3 | 153, 146, 433, 63 |
| 3 | 51, 146, 433, 21 |
| 17, 146, 433, 7 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 3 x 17 x 146 x 433 x 7 = 203119434
Therefore, the lowest common multiple of 459,438,433,189 is 203119434.
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.
459 x 438 x 433 x 189 = 16452674154
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.
459 : 1, 3, 9, 17, 27, 51, 153, 459
438 : 1, 2, 3, 6, 73, 146, 219, 438
433 : 1, 433
189 : 1, 3, 7, 9, 21, 27, 63, 189
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 459,438,433,189, is 1.
Now, the common factors can be found like this.
459:3x 3x 3x 17
438:2x 3x 73
433:433
189:3x 3x 3x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 3 = 81
Therefore, the value for common factors is 81.
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 = 16452674154/(1x81)
LCM = 16452674154/81
LCM = 203119434
Thus, we can understand that the LCM of 459,438,433,189 is 203119434.
