Given numbers are 797,782,805,805
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 797,782,805,805 is 21813890.
Find LCM of 797,782,805,805 with Prime Factorization
| 5 | 797, 782, 805, 805 |
| 7 | 797, 782, 161, 161 |
| 23 | 797, 782, 23, 23 |
| 797, 34, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
5 x 7 x 23 x 797 x 34 x 1 x 1 = 21813890
Therefore, the lowest common multiple of 797,782,805,805 is 21813890.
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.
797 x 782 x 805 x 805 = 403884173350
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.
797 : 1, 797
782 : 1, 2, 17, 23, 34, 46, 391, 782
805 : 1, 5, 7, 23, 35, 115, 161, 805
805 : 1, 5, 7, 23, 35, 115, 161, 805
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 797,782,805,805, is 1.
Now, the common factors can be found like this.
797:797
782:2x 17x 23
805:5x 7x 23
805:5x 7x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 7x 23x 23 = 18515
Therefore, the value for common factors is 18515.
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 = 403884173350/(1x18515)
LCM = 403884173350/18515
LCM = 21813890
Thus, we can understand that the LCM of 797,782,805,805 is 21813890.
