Given numbers are 686,286,955,585
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 686,286,955,585 is 843152310.
Find LCM of 686,286,955,585 with Prime Factorization
| 2 | 686, 286, 955, 585 |
| 5 | 343, 143, 955, 585 |
| 13 | 343, 143, 191, 117 |
| 343, 11, 191, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 13 x 343 x 11 x 191 x 9 = 843152310
Therefore, the lowest common multiple of 686,286,955,585 is 843152310.
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.
686 x 286 x 955 x 585 = 109609800300
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.
686 : 1, 2, 7, 14, 49, 98, 343, 686
286 : 1, 2, 11, 13, 22, 26, 143, 286
955 : 1, 5, 191, 955
585 : 1, 3, 5, 9, 13, 15, 39, 45, 65, 117, 195, 585
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 686,286,955,585, is 1.
Now, the common factors can be found like this.
686:2x 7x 7x 7
286:2x 11x 13
955:5x 191
585:3x 3x 5x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 13 = 130
Therefore, the value for common factors is 130.
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 = 109609800300/(1x130)
LCM = 109609800300/130
LCM = 843152310
Thus, we can understand that the LCM of 686,286,955,585 is 843152310.
