Given numbers are 105,147,315,303,885
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 105,147,315,303,885 is 13139595.
Find LCM of 105,147,315,303,885 with Prime Factorization
| 3 | 105, 147, 315, 303, 885 |
| 5 | 35, 49, 105, 101, 295 |
| 7 | 7, 49, 21, 101, 59 |
| 1, 7, 3, 101, 59 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 7 x 1 x 7 x 3 x 101 x 59 = 13139595
Therefore, the lowest common multiple of 105,147,315,303,885 is 13139595.
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.
105 x 147 x 315 x 303 x 885 = 1303776313875
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.
105 : 1, 3, 5, 7, 15, 21, 35, 105
147 : 1, 3, 7, 21, 49, 147
315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315
303 : 1, 3, 101, 303
885 : 1, 3, 5, 15, 59, 177, 295, 885
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 105,147,315,303,885, is 3.
Now, the common factors can be found like this.
105:3x 5x 7
147:3x 7x 7
315:3x 3x 5x 7
303:3x 101
885:3x 5x 59
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 5x 5x 7x 7 = 33075
Therefore, the value for common factors is 33075.
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 = 1303776313875/(3x33075)
LCM = 1303776313875/99225
LCM = 13139595
Thus, we can understand that the LCM of 105,147,315,303,885 is 13139595.
