Find LCM of 714,720,868,713,243 with Prime Factorization
| 2 | 714, 720, 868, 713, 243 |
| 2 | 357, 360, 434, 713, 243 |
| 3 | 357, 180, 217, 713, 243 |
| 3 | 119, 60, 217, 713, 81 |
| 7 | 119, 20, 217, 713, 27 |
| 31 | 17, 20, 31, 713, 27 |
| 17, 20, 1, 23, 27 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 7 x 31 x 17 x 20 x 1 x 23 x 27 = 1649425680
Therefore, the lowest common multiple of 714,720,868,713,243 is 1649425680.
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.
714 x 720 x 868 x 713 x 243 = 77311880472960
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.
714 : 1, 2, 3, 6, 7, 14, 17, 21, 34, 42, 51, 102, 119, 238, 357, 714
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
868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868
713 : 1, 23, 31, 713
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 714,720,868,713,243, is 1.
Now, the common factors can be found like this.
714:2x 3x 7x 17
720:2x 2x 2x 2x 3x 3x 5
868:2x 2x 7x 31
713:23x 31
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.
2x 2x 2x 3x 3x 3x 7x 31 = 46872
Therefore, the value for common factors is 46872.
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 = 77311880472960/(1x46872)
LCM = 77311880472960/46872
LCM = 1649425680
Thus, we can understand that the LCM of 714,720,868,713,243 is 1649425680.
