Find LCM of 828,756,756,738 with Prime Factorization
| 2 | 828, 756, 756, 738 |
| 2 | 414, 378, 378, 369 |
| 3 | 207, 189, 189, 369 |
| 3 | 69, 63, 63, 123 |
| 3 | 23, 21, 21, 41 |
| 7 | 23, 7, 7, 41 |
| 23, 1, 1, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 3 x 7 x 23 x 1 x 1 x 41 = 712908
Therefore, the lowest common multiple of 828,756,756,738 is 712908.
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.
828 x 756 x 756 x 738 = 349245074304
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.
828 : 1, 2, 3, 4, 6, 9, 12, 18, 23, 36, 46, 69, 92, 138, 207, 276, 414, 828
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
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
18 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 828,756,756,738, is 18.
Now, the common factors can be found like this.
828:2x 2x 3x 3x 23
756:2x 2x 3x 3x 3x 7
756:2x 2x 3x 3x 3x 7
738:2x 3x 3x 41
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 = 349245074304/(18x27216)
LCM = 349245074304/489888
LCM = 712908
Thus, we can understand that the LCM of 828,756,756,738 is 712908.
