Given numbers are 561,605,845,462
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 561,605,845,462 is 73002930.
Find LCM of 561,605,845,462 with Prime Factorization
| 3 | 561, 605, 845, 462 |
| 5 | 187, 605, 845, 154 |
| 11 | 187, 121, 169, 154 |
| 17, 11, 169, 14 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 11 x 17 x 11 x 169 x 14 = 73002930
Therefore, the lowest common multiple of 561,605,845,462 is 73002930.
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 605 x 845 x 462 = 132500317950
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
605 : 1, 5, 11, 55, 121, 605
845 : 1, 5, 13, 65, 169, 845
462 : 1, 2, 3, 6, 7, 11, 14, 21, 22, 33, 42, 66, 77, 154, 231, 462
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,605,845,462, is 1.
Now, the common factors can be found like this.
561:3x 11x 17
605:5x 11x 11
845:5x 13x 13
462:2x 3x 7x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 11x 11 = 1815
Therefore, the value for common factors is 1815.
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 = 132500317950/(1x1815)
LCM = 132500317950/1815
LCM = 73002930
Thus, we can understand that the LCM of 561,605,845,462 is 73002930.
