Given numbers are 470,121,165,969,243
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 470,121,165,969,243 is 4463669430.
Find LCM of 470,121,165,969,243 with Prime Factorization
| 3 | 470, 121, 165, 969, 243 |
| 5 | 470, 121, 55, 323, 81 |
| 11 | 94, 121, 11, 323, 81 |
| 94, 1, 11, 323, 81 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 11 x 94 x 1 x 11 x 323 x 81 = 4463669430
Therefore, the lowest common multiple of 470,121,165,969,243 is 4463669430.
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.
470 x 121 x 165 x 969 x 243 = 2209516367850
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.
470 : 1, 2, 5, 10, 47, 94, 235, 470
121 : 1, 11, 121
165 : 1, 3, 5, 11, 15, 33, 55, 165
969 : 1, 3, 17, 19, 51, 57, 323, 969
243 : 1, 3, 9, 27, 81, 243
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 470,121,165,969,243, is 1.
Now, the common factors can be found like this.
470:2x 5x 47
121:11x 11
165:3x 5x 11
969:3x 17x 19
243:3x 3x 3x 3x 3
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 5x 11 = 495
Therefore, the value for common factors is 495.
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 = 2209516367850/(1x495)
LCM = 2209516367850/495
LCM = 4463669430
Thus, we can understand that the LCM of 470,121,165,969,243 is 4463669430.
