Given numbers are 247,206,837,945,915
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 247,206,837,945,915 is 90925879590.
Find LCM of 247,206,837,945,915 with Prime Factorization
| 3 | 247, 206, 837, 945, 915 |
| 3 | 247, 206, 279, 315, 305 |
| 3 | 247, 206, 93, 105, 305 |
| 5 | 247, 206, 31, 35, 305 |
| 247, 206, 31, 7, 61 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 3 x 5 x 247 x 206 x 31 x 7 x 61 = 90925879590
Therefore, the lowest common multiple of 247,206,837,945,915 is 90925879590.
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.
247 x 206 x 837 x 945 x 915 = 36824981233950
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.
247 : 1, 13, 19, 247
206 : 1, 2, 103, 206
837 : 1, 3, 9, 27, 31, 93, 279, 837
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
915 : 1, 3, 5, 15, 61, 183, 305, 915
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 247,206,837,945,915, is 1.
Now, the common factors can be found like this.
247:13x 19
206:2x 103
837:3x 3x 3x 31
945:3x 3x 3x 5x 7
915:3x 5x 61
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 3x 5 = 405
Therefore, the value for common factors is 405.
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 = 36824981233950/(1x405)
LCM = 36824981233950/405
LCM = 90925879590
Thus, we can understand that the LCM of 247,206,837,945,915 is 90925879590.
