Find LCM of 291,505,243,836,960 with Prime Factorization
| 2 | 291, 505, 243, 836, 960 |
| 2 | 291, 505, 243, 418, 480 |
| 3 | 291, 505, 243, 209, 240 |
| 5 | 97, 505, 81, 209, 80 |
| 97, 101, 81, 209, 16 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 97 x 101 x 81 x 209 x 16 = 159219276480
Therefore, the lowest common multiple of 291,505,243,836,960 is 159219276480.
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.
291 x 505 x 243 x 836 x 960 = 28659469766400
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.
291 : 1, 3, 97, 291
505 : 1, 5, 101, 505
243 : 1, 3, 9, 27, 81, 243
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
960 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 64, 80, 96, 120, 160, 192, 240, 320, 480, 960
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 291,505,243,836,960, is 1.
Now, the common factors can be found like this.
291:3x 97
505:5x 101
243:3x 3x 3x 3x 3
836:2x 2x 11x 19
960:2x 2x 2x 2x 2x 2x 3x 5
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 3x 3x 5 = 180
Therefore, the value for common factors is 180.
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 = 28659469766400/(1x180)
LCM = 28659469766400/180
LCM = 159219276480
Thus, we can understand that the LCM of 291,505,243,836,960 is 159219276480.
