Find LCM of 720,154,231,431,227 with Prime Factorization
| 2 | 720, 154, 231, 431, 227 |
| 3 | 360, 77, 231, 431, 227 |
| 7 | 120, 77, 77, 431, 227 |
| 11 | 120, 11, 11, 431, 227 |
| 120, 1, 1, 431, 227 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 11 x 120 x 1 x 1 x 431 x 227 = 5424083280
Therefore, the lowest common multiple of 720,154,231,431,227 is 5424083280.
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.
720 x 154 x 231 x 431 x 227 = 2505926475360
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.
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
154 : 1, 2, 7, 11, 14, 22, 77, 154
231 : 1, 3, 7, 11, 21, 33, 77, 231
431 : 1, 431
227 : 1, 227
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 720,154,231,431,227, is 1.
Now, the common factors can be found like this.
720:2x 2x 2x 2x 3x 3x 5
154:2x 7x 11
231:3x 7x 11
431:431
227:227
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 7x 11 = 462
Therefore, the value for common factors is 462.
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 = 2505926475360/(1x462)
LCM = 2505926475360/462
LCM = 5424083280
Thus, we can understand that the LCM of 720,154,231,431,227 is 5424083280.
