Find LCM of 957,341,990,945 with Prime Factorization
| 3 | 957, 341, 990, 945 |
| 3 | 319, 341, 330, 315 |
| 5 | 319, 341, 110, 105 |
| 11 | 319, 341, 22, 21 |
| 29, 31, 2, 21 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 11 x 29 x 31 x 2 x 21 = 18690210
Therefore, the lowest common multiple of 957,341,990,945 is 18690210.
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.
957 x 341 x 990 x 945 = 305304580350
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.
957 : 1, 3, 11, 29, 33, 87, 319, 957
341 : 1, 11, 31, 341
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 957,341,990,945, is 1.
Now, the common factors can be found like this.
957:3x 11x 29
341:11x 31
990:2x 3x 3x 5x 11
945:3x 3x 3x 5x 7
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 11x 11 = 16335
Therefore, the value for common factors is 16335.
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 = 305304580350/(1x16335)
LCM = 305304580350/16335
LCM = 18690210
Thus, we can understand that the LCM of 957,341,990,945 is 18690210.
