Given numbers are 259,640,922,686
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 259,640,922,686 is 3744352640.
Find LCM of 259,640,922,686 with Prime Factorization
| 2 | 259, 640, 922, 686 |
| 7 | 259, 320, 461, 343 |
| 37, 320, 461, 49 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 37 x 320 x 461 x 49 = 3744352640
Therefore, the lowest common multiple of 259,640,922,686 is 3744352640.
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.
259 x 640 x 922 x 686 = 104841873920
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.
259 : 1, 7, 37, 259
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
922 : 1, 2, 461, 922
686 : 1, 2, 7, 14, 49, 98, 343, 686
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 259,640,922,686, is 1.
Now, the common factors can be found like this.
259:7x 37
640:2x 2x 2x 2x 2x 2x 2x 5
922:2x 461
686:2x 7x 7x 7
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 7 = 28
Therefore, the value for common factors is 28.
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 = 104841873920/(1x28)
LCM = 104841873920/28
LCM = 3744352640
Thus, we can understand that the LCM of 259,640,922,686 is 3744352640.
