Given numbers are 326,409,355,878
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 326,409,355,878 is 20779437230.
Find LCM of 326,409,355,878 with Prime Factorization
| 2 | 326, 409, 355, 878 |
| 163, 409, 355, 439 |
Multiply the prime numbers at the bottom and the left side.
2 x 163 x 409 x 355 x 439 = 20779437230
Therefore, the lowest common multiple of 326,409,355,878 is 20779437230.
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.
326 x 409 x 355 x 878 = 41558874460
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.
326 : 1, 2, 163, 326
409 : 1, 409
355 : 1, 5, 71, 355
878 : 1, 2, 439, 878
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 326,409,355,878, is 1.
Now, the common factors can be found like this.
326:2x 163
409:409
355:5x 71
878:2x 439
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 41558874460/(1x2)
LCM = 41558874460/2
LCM = 20779437230
Thus, we can understand that the LCM of 326,409,355,878 is 20779437230.
