Given numbers are 831,526,540,726,545
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 831,526,540,726,545 is 518849193060.
Find LCM of 831,526,540,726,545 with Prime Factorization
| 2 | 831, 526, 540, 726, 545 |
| 3 | 831, 263, 270, 363, 545 |
| 5 | 277, 263, 90, 121, 545 |
| 277, 263, 18, 121, 109 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 277 x 263 x 18 x 121 x 109 = 518849193060
Therefore, the lowest common multiple of 831,526,540,726,545 is 518849193060.
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.
831 x 526 x 540 x 726 x 545 = 93392854750800
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.
831 : 1, 3, 277, 831
526 : 1, 2, 263, 526
540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540
726 : 1, 2, 3, 6, 11, 22, 33, 66, 121, 242, 363, 726
545 : 1, 5, 109, 545
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 831,526,540,726,545, is 1.
Now, the common factors can be found like this.
831:3x 277
526:2x 263
540:2x 2x 3x 3x 3x 5
726:2x 3x 11x 11
545:5x 109
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 3x 3x 5 = 180
Therefore, the value for common factors is 180.
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 = 93392854750800/(1x180)
LCM = 93392854750800/180
LCM = 518849193060
Thus, we can understand that the LCM of 831,526,540,726,545 is 518849193060.
