Find LCM of 270,270,756,738,684 with Prime Factorization
| 2 | 270, 270, 756, 738, 684 |
| 2 | 135, 135, 378, 369, 342 |
| 3 | 135, 135, 189, 369, 171 |
| 3 | 45, 45, 63, 123, 57 |
| 3 | 15, 15, 21, 41, 19 |
| 5 | 5, 5, 7, 41, 19 |
| 1, 1, 7, 41, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 3 x 5 x 1 x 1 x 7 x 41 x 19 = 2944620
Therefore, the lowest common multiple of 270,270,756,738,684 is 2944620.
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.
270 x 270 x 756 x 738 x 684 = 27820298620800
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.
270 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 90, 135, 270
270 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 90, 135, 270
756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756
738 : 1, 2, 3, 6, 9, 18, 41, 82, 123, 246, 369, 738
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
18 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 270,270,756,738,684, is 18.
Now, the common factors can be found like this.
270:2x 3x 3x 3x 5
270:2x 3x 3x 3x 5
756:2x 2x 3x 3x 3x 7
738:2x 3x 3x 41
684:2x 2x 3x 3x 19
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 3x 3x 3x 5 = 524880
Therefore, the value for common factors is 524880.
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 = 27820298620800/(18x524880)
LCM = 27820298620800/9447840
LCM = 2944620
Thus, we can understand that the LCM of 270,270,756,738,684 is 2944620.
