Given numbers are 459,646,653,209
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 459,646,653,209 is 125285886.
Find LCM of 459,646,653,209 with Prime Factorization
| 17 | 459, 646, 653, 209 |
| 19 | 27, 38, 653, 209 |
| 27, 2, 653, 11 |
Multiply the prime numbers at the bottom and the left side.
17 x 19 x 27 x 2 x 653 x 11 = 125285886
Therefore, the lowest common multiple of 459,646,653,209 is 125285886.
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 646 x 653 x 209 = 40467341178
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
646 : 1, 2, 17, 19, 34, 38, 323, 646
653 : 1, 653
209 : 1, 11, 19, 209
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 459,646,653,209, is 1.
Now, the common factors can be found like this.
459:3x 3x 3x 17
646:2x 17x 19
653:653
209:11x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
17x 19 = 323
Therefore, the value for common factors is 323.
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 = 40467341178/(1x323)
LCM = 40467341178/323
LCM = 125285886
Thus, we can understand that the LCM of 459,646,653,209 is 125285886.
