Given numbers are 845,621,659,693,895
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 845,621,659,693,895 is 4766257260765.
Find LCM of 845,621,659,693,895 with Prime Factorization
| 3 | 845, 621, 659, 693, 895 |
| 3 | 845, 207, 659, 231, 895 |
| 5 | 845, 69, 659, 77, 895 |
| 169, 69, 659, 77, 179 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 169 x 69 x 659 x 77 x 179 = 4766257260765
Therefore, the lowest common multiple of 845,621,659,693,895 is 4766257260765.
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.
845 x 621 x 659 x 693 x 895 = 214481576734425
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.
845 : 1, 5, 13, 65, 169, 845
621 : 1, 3, 9, 23, 27, 69, 207, 621
659 : 1, 659
693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693
895 : 1, 5, 179, 895
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 845,621,659,693,895, is 1.
Now, the common factors can be found like this.
845:5x 13x 13
621:3x 3x 3x 23
659:659
693:3x 3x 7x 11
895:5x 179
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 5 = 45
Therefore, the value for common factors is 45.
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 = 214481576734425/(1x45)
LCM = 214481576734425/45
LCM = 4766257260765
Thus, we can understand that the LCM of 845,621,659,693,895 is 4766257260765.
