Find LCM of 720,252,258,322,747 with Prime Factorization
| 2 | 720, 252, 258, 322, 747 |
| 2 | 360, 126, 129, 161, 747 |
| 3 | 180, 63, 129, 161, 747 |
| 3 | 60, 21, 43, 161, 249 |
| 7 | 20, 7, 43, 161, 83 |
| 20, 1, 43, 23, 83 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 7 x 20 x 1 x 43 x 23 x 83 = 413718480
Therefore, the lowest common multiple of 720,252,258,322,747 is 413718480.
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 252 x 258 x 322 x 747 = 11259762151680
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
252 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 28, 36, 42, 63, 84, 126, 252
258 : 1, 2, 3, 6, 43, 86, 129, 258
322 : 1, 2, 7, 14, 23, 46, 161, 322
747 : 1, 3, 9, 83, 249, 747
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 720,252,258,322,747, is 1.
Now, the common factors can be found like this.
720:2x 2x 2x 2x 3x 3x 5
252:2x 2x 3x 3x 7
258:2x 3x 43
322:2x 7x 23
747:3x 3x 83
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 2x 2x 3x 3x 3x 3x 3x 7 = 27216
Therefore, the value for common factors is 27216.
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 = 11259762151680/(1x27216)
LCM = 11259762151680/27216
LCM = 413718480
Thus, we can understand that the LCM of 720,252,258,322,747 is 413718480.
