Given numbers are 326,442,251,574,780
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 326,442,251,574,780 is 155699331060.
Find LCM of 326,442,251,574,780 with Prime Factorization
| 2 | 326, 442, 251, 574, 780 |
| 13 | 163, 221, 251, 287, 390 |
| 163, 17, 251, 287, 30 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 163 x 17 x 251 x 287 x 30 = 155699331060
Therefore, the lowest common multiple of 326,442,251,574,780 is 155699331060.
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 442 x 251 x 574 x 780 = 16192730430240
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
442 : 1, 2, 13, 17, 26, 34, 221, 442
251 : 1, 251
574 : 1, 2, 7, 14, 41, 82, 287, 574
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 326,442,251,574,780, is 1.
Now, the common factors can be found like this.
326:2x 163
442:2x 13x 17
251:251
574:2x 7x 41
780:2x 2x 3x 5x 13
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 2x 13 = 104
Therefore, the value for common factors is 104.
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 = 16192730430240/(1x104)
LCM = 16192730430240/104
LCM = 155699331060
Thus, we can understand that the LCM of 326,442,251,574,780 is 155699331060.
