Given numbers are 585,821,821,783
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 585,821,821,783 is 41784795.
Find LCM of 585,821,821,783 with Prime Factorization
| 3 | 585, 821, 821, 783 |
| 3 | 195, 821, 821, 261 |
| 821 | 65, 821, 821, 87 |
| 65, 1, 1, 87 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 821 x 65 x 1 x 1 x 87 = 41784795
Therefore, the lowest common multiple of 585,821,821,783 is 41784795.
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.
585 x 821 x 821 x 783 = 308747850255
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.
585 : 1, 3, 5, 9, 13, 15, 39, 45, 65, 117, 195, 585
821 : 1, 821
821 : 1, 821
783 : 1, 3, 9, 27, 29, 87, 261, 783
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 585,821,821,783, is 1.
Now, the common factors can be found like this.
585:3x 3x 5x 13
821:821
821:821
783:3x 3x 3x 29
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 821 = 7389
Therefore, the value for common factors is 7389.
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 = 308747850255/(1x7389)
LCM = 308747850255/7389
LCM = 41784795
Thus, we can understand that the LCM of 585,821,821,783 is 41784795.
