The LCM of 783,841,722,756 is 229522356.
Find LCM of 783,841,722,756 with Prime Factorization
| 2 | 783, 841, 722, 756 |
| 3 | 783, 841, 361, 378 |
| 3 | 261, 841, 361, 126 |
| 3 | 87, 841, 361, 42 |
| 29 | 29, 841, 361, 14 |
| 1, 29, 361, 14 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 29 x 1 x 29 x 361 x 14 = 229522356
Therefore, the lowest common multiple of 783,841,722,756 is 229522356.
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.
783 x 841 x 722 x 756 = 359432009496
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.
783 : 1, 3, 9, 27, 29, 87, 261, 783
841 : 1, 29, 841
722 : 1, 2, 19, 38, 361, 722
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
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 783,841,722,756, is 1.
Now, the common factors can be found like this.
783:3x 3x 3x 29
841:29x 29
722:2x 19x 19
756:2x 2x 3x 3x 3x 7
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 29 = 1566
Therefore, the value for common factors is 1566.
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 = 359432009496/(1x1566)
LCM = 359432009496/1566
LCM = 229522356
Thus, we can understand that the LCM of 783,841,722,756 is 229522356.
