Given numbers are 561,670,910,726,285
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 561,670,910,726,285 is 7148671530.
Find LCM of 561,670,910,726,285 with Prime Factorization
| 2 | 561, 670, 910, 726, 285 |
| 3 | 561, 335, 455, 363, 285 |
| 5 | 187, 335, 455, 121, 95 |
| 11 | 187, 67, 91, 121, 19 |
| 17, 67, 91, 11, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 11 x 17 x 67 x 91 x 11 x 19 = 7148671530
Therefore, the lowest common multiple of 561,670,910,726,285 is 7148671530.
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 670 x 910 x 726 x 285 = 70771848147000
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
670 : 1, 2, 5, 10, 67, 134, 335, 670
910 : 1, 2, 5, 7, 10, 13, 14, 26, 35, 65, 70, 91, 130, 182, 455, 910
726 : 1, 2, 3, 6, 11, 22, 33, 66, 121, 242, 363, 726
285 : 1, 3, 5, 15, 19, 57, 95, 285
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,670,910,726,285, is 1.
Now, the common factors can be found like this.
561:3x 11x 17
670:2x 5x 67
910:2x 5x 7x 13
726:2x 3x 11x 11
285:3x 5x 19
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 5x 5x 11 = 9900
Therefore, the value for common factors is 9900.
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 = 70771848147000/(1x9900)
LCM = 70771848147000/9900
LCM = 7148671530
Thus, we can understand that the LCM of 561,670,910,726,285 is 7148671530.
