Given numbers are 315,185,665,161,818
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 315,185,665,161,818 is 4166266230.
Find LCM of 315,185,665,161,818 with Prime Factorization
| 5 | 315, 185, 665, 161, 818 |
| 7 | 63, 37, 133, 161, 818 |
| 9, 37, 19, 23, 818 |
Multiply the prime numbers at the bottom and the left side.
5 x 7 x 9 x 37 x 19 x 23 x 818 = 4166266230
Therefore, the lowest common multiple of 315,185,665,161,818 is 4166266230.
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.
315 x 185 x 665 x 161 x 818 = 5103676131750
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.
315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315
185 : 1, 5, 37, 185
665 : 1, 5, 7, 19, 35, 95, 133, 665
161 : 1, 7, 23, 161
818 : 1, 2, 409, 818
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 315,185,665,161,818, is 1.
Now, the common factors can be found like this.
315:3x 3x 5x 7
185:5x 37
665:5x 7x 19
161:7x 23
818:2x 409
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 5x 7x 7 = 1225
Therefore, the value for common factors is 1225.
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 = 5103676131750/(1x1225)
LCM = 5103676131750/1225
LCM = 4166266230
Thus, we can understand that the LCM of 315,185,665,161,818 is 4166266230.
