Find LCM of 405,635,243,916,945 with Prime Factorization
| 3 | 405, 635, 243, 916, 945 |
| 3 | 135, 635, 81, 916, 315 |
| 3 | 45, 635, 27, 916, 105 |
| 3 | 15, 635, 9, 916, 35 |
| 5 | 5, 635, 3, 916, 35 |
| 1, 127, 3, 916, 7 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 3 x 3 x 5 x 1 x 127 x 3 x 916 x 7 = 989403660
Therefore, the lowest common multiple of 405,635,243,916,945 is 989403660.
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.
405 x 635 x 243 x 916 x 945 = 54095645110500
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.
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
635 : 1, 5, 127, 635
243 : 1, 3, 9, 27, 81, 243
916 : 1, 2, 4, 229, 458, 916
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 405,635,243,916,945, is 1.
Now, the common factors can be found like this.
405:3x 3x 3x 3x 5
635:5x 127
243:3x 3x 3x 3x 3
916:2x 2x 229
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 3x 3x 3x 3x 5x 5 = 54675
Therefore, the value for common factors is 54675.
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 = 54095645110500/(1x54675)
LCM = 54095645110500/54675
LCM = 989403660
Thus, we can understand that the LCM of 405,635,243,916,945 is 989403660.
