Find LCM of 738,645,816,969,975 with Prime Factorization
| 2 | 738, 645, 816, 969, 975 |
| 3 | 369, 645, 408, 969, 975 |
| 5 | 123, 215, 136, 323, 325 |
| 17 | 123, 43, 136, 323, 65 |
| 123, 43, 8, 19, 65 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 17 x 123 x 43 x 8 x 19 x 65 = 26650213200
Therefore, the lowest common multiple of 738,645,816,969,975 is 26650213200.
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.
738 x 645 x 816 x 969 x 975 = 366973435764000
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.
738 : 1, 2, 3, 6, 9, 18, 41, 82, 123, 246, 369, 738
645 : 1, 3, 5, 15, 43, 129, 215, 645
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
969 : 1, 3, 17, 19, 51, 57, 323, 969
975 : 1, 3, 5, 13, 15, 25, 39, 65, 75, 195, 325, 975
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 738,645,816,969,975, is 3.
Now, the common factors can be found like this.
738:2x 3x 3x 41
645:3x 5x 43
816:2x 2x 2x 2x 3x 17
969:3x 17x 19
975:3x 5x 5x 13
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 3x 3x 5x 17 = 4590
Therefore, the value for common factors is 4590.
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 = 366973435764000/(3x4590)
LCM = 366973435764000/13770
LCM = 26650213200
Thus, we can understand that the LCM of 738,645,816,969,975 is 26650213200.
