Given numbers are 405,646,323,375
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 405,646,323,375 is 6540750.
Find LCM of 405,646,323,375 with Prime Factorization
3 | 405, 646, 323, 375 |
5 | 135, 646, 323, 125 |
17 | 27, 646, 323, 25 |
19 | 27, 38, 19, 25 |
27, 2, 1, 25 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 17 x 19 x 27 x 2 x 1 x 25 = 6540750
Therefore, the lowest common multiple of 405,646,323,375 is 6540750.
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.
405 x 646 x 323 x 375 = 31689933750
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.
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
646 : 1, 2, 17, 19, 34, 38, 323, 646
323 : 1, 17, 19, 323
375 : 1, 3, 5, 15, 25, 75, 125, 375
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 405,646,323,375, is 1.
Now, the common factors can be found like this.
405:3x 3x 3x 3x 5
646:2x 17x 19
323:17x 19
375:3x 5x 5x 5
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 17x 19 = 4845
Therefore, the value for common factors is 4845.
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 = 31689933750/(1x4845)
LCM = 31689933750/4845
LCM = 6540750
Thus, we can understand that the LCM of 405,646,323,375 is 6540750.
