Given numbers are 326,287,917,744,442
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 326,287,917,744,442 is 1007641407864.
Find LCM of 326,287,917,744,442 with Prime Factorization
| 2 | 326, 287, 917, 744, 442 |
| 7 | 163, 287, 917, 372, 221 |
| 163, 41, 131, 372, 221 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 163 x 41 x 131 x 372 x 221 = 1007641407864
Therefore, the lowest common multiple of 326,287,917,744,442 is 1007641407864.
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 287 x 917 x 744 x 442 = 28213959420192
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
287 : 1, 7, 41, 287
917 : 1, 7, 131, 917
744 : 1, 2, 3, 4, 6, 8, 12, 24, 31, 62, 93, 124, 186, 248, 372, 744
442 : 1, 2, 13, 17, 26, 34, 221, 442
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 326,287,917,744,442, is 1.
Now, the common factors can be found like this.
326:2x 163
287:7x 41
917:7x 131
744:2x 2x 2x 3x 31
442:2x 13x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 7 = 28
Therefore, the value for common factors is 28.
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 = 28213959420192/(1x28)
LCM = 28213959420192/28
LCM = 1007641407864
Thus, we can understand that the LCM of 326,287,917,744,442 is 1007641407864.
