Given numbers are 561,831,705,323,374
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 561,831,705,323,374 is 1387695210.
Find LCM of 561,831,705,323,374 with Prime Factorization
| 3 | 561, 831, 705, 323, 374 |
| 11 | 187, 277, 235, 323, 374 |
| 17 | 17, 277, 235, 323, 34 |
| 1, 277, 235, 19, 2 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 17 x 1 x 277 x 235 x 19 x 2 = 1387695210
Therefore, the lowest common multiple of 561,831,705,323,374 is 1387695210.
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.
561 x 831 x 705 x 323 x 374 = 39703347653310
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.
561 : 1, 3, 11, 17, 33, 51, 187, 561
831 : 1, 3, 277, 831
705 : 1, 3, 5, 15, 47, 141, 235, 705
323 : 1, 17, 19, 323
374 : 1, 2, 11, 17, 22, 34, 187, 374
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,831,705,323,374, is 1.
Now, the common factors can be found like this.
561:3x 11x 17
831:3x 277
705:3x 5x 47
323:17x 19
374:2x 11x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 11x 17x 17 = 28611
Therefore, the value for common factors is 28611.
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 = 39703347653310/(1x28611)
LCM = 39703347653310/28611
LCM = 1387695210
Thus, we can understand that the LCM of 561,831,705,323,374 is 1387695210.
