Find LCM of 260,867,400,585,646 with Prime Factorization
| 2 | 260, 867, 400, 585, 646 |
| 2 | 130, 867, 200, 585, 323 |
| 3 | 65, 867, 100, 585, 323 |
| 5 | 65, 289, 100, 195, 323 |
| 13 | 13, 289, 20, 39, 323 |
| 17 | 1, 289, 20, 3, 323 |
| 1, 17, 20, 3, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 13 x 17 x 1 x 17 x 20 x 3 x 19 = 256978800
Therefore, the lowest common multiple of 260,867,400,585,646 is 256978800.
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.
260 x 867 x 400 x 585 x 646 = 34075388880000
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.
260 : 1, 2, 4, 5, 10, 13, 20, 26, 52, 65, 130, 260
867 : 1, 3, 17, 51, 289, 867
400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400
585 : 1, 3, 5, 9, 13, 15, 39, 45, 65, 117, 195, 585
646 : 1, 2, 17, 19, 34, 38, 323, 646
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 260,867,400,585,646, is 1.
Now, the common factors can be found like this.
260:2x 2x 5x 13
867:3x 17x 17
400:2x 2x 2x 2x 5x 5
585:3x 3x 5x 13
646:2x 17x 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 2x 3x 5x 5x 13x 17 = 132600
Therefore, the value for common factors is 132600.
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 = 34075388880000/(1x132600)
LCM = 34075388880000/132600
LCM = 256978800
Thus, we can understand that the LCM of 260,867,400,585,646 is 256978800.
