Given numbers are 323,865,431,646
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 323,865,431,646 is 240838490.
Find LCM of 323,865,431,646 with Prime Factorization
| 17 | 323, 865, 431, 646 |
| 19 | 19, 865, 431, 38 |
| 1, 865, 431, 2 |
Multiply the prime numbers at the bottom and the left side.
17 x 19 x 1 x 865 x 431 x 2 = 240838490
Therefore, the lowest common multiple of 323,865,431,646 is 240838490.
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.
323 x 865 x 431 x 646 = 77790832270
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.
323 : 1, 17, 19, 323
865 : 1, 5, 173, 865
431 : 1, 431
646 : 1, 2, 17, 19, 34, 38, 323, 646
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 323,865,431,646, is 1.
Now, the common factors can be found like this.
323:17x 19
865:5x 173
431:431
646:2x 17x 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 = 77790832270/(1x323)
LCM = 77790832270/323
LCM = 240838490
Thus, we can understand that the LCM of 323,865,431,646 is 240838490.
