Given numbers are 585,685,791
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 585,685,791 is 63394695.
Find LCM of 585,685,791 with Prime Factorization
| 5 | 585, 685, 791 |
| 117, 137, 791 |
Multiply the prime numbers at the bottom and the left side.
5 x 117 x 137 x 791 = 63394695
Therefore, the lowest common multiple of 585,685,791 is 63394695.
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 685 x 791 = 316973475
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
685 : 1, 5, 137, 685
791 : 1, 7, 113, 791
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 585,685,791, is 1.
Now, the common factors can be found like this.
585:3x 3x 5x 13
685:5x 137
791:7x 113
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5 = 5
Therefore, the value for common factors is 5.
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 = 316973475/(1x5)
LCM = 316973475/5
LCM = 63394695
Thus, we can understand that the LCM of 585,685,791 is 63394695.
