Given numbers are 815,816,812,197
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 815,816,812,197 is 26595614640.
Find LCM of 815,816,812,197 with Prime Factorization
| 2 | 815, 816, 812, 197 |
| 2 | 815, 408, 406, 197 |
| 815, 204, 203, 197 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 815 x 204 x 203 x 197 = 26595614640
Therefore, the lowest common multiple of 815,816,812,197 is 26595614640.
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.
815 x 816 x 812 x 197 = 106382458560
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.
815 : 1, 5, 163, 815
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
197 : 1, 197
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 815,816,812,197, is 1.
Now, the common factors can be found like this.
815:5x 163
816:2x 2x 2x 2x 3x 17
812:2x 2x 7x 29
197:197
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2 = 4
Therefore, the value for common factors is 4.
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 = 106382458560/(1x4)
LCM = 106382458560/4
LCM = 26595614640
Thus, we can understand that the LCM of 815,816,812,197 is 26595614640.
