Given numbers are 685,732,585,976
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 685,732,585,976 is 78221520.
Find LCM of 685,732,585,976 with Prime Factorization
| 2 | 685, 732, 585, 976 |
| 2 | 685, 366, 585, 488 |
| 3 | 685, 183, 585, 244 |
| 5 | 685, 61, 195, 244 |
| 61 | 137, 61, 39, 244 |
| 137, 1, 39, 4 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 61 x 137 x 1 x 39 x 4 = 78221520
Therefore, the lowest common multiple of 685,732,585,976 is 78221520.
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.
685 x 732 x 585 x 976 = 286290763200
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.
685 : 1, 5, 137, 685
732 : 1, 2, 3, 4, 6, 12, 61, 122, 183, 244, 366, 732
585 : 1, 3, 5, 9, 13, 15, 39, 45, 65, 117, 195, 585
976 : 1, 2, 4, 8, 16, 61, 122, 244, 488, 976
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 685,732,585,976, is 1.
Now, the common factors can be found like this.
685:5x 137
732:2x 2x 3x 61
585:3x 3x 5x 13
976:2x 2x 2x 2x 61
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 3x 5x 61 = 3660
Therefore, the value for common factors is 3660.
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 = 286290763200/(1x3660)
LCM = 286290763200/3660
LCM = 78221520
Thus, we can understand that the LCM of 685,732,585,976 is 78221520.
