The LCM of 783,405,497,910 is 151768890.
Find LCM of 783,405,497,910 with Prime Factorization
| 3 | 783, 405, 497, 910 |
| 3 | 261, 135, 497, 910 |
| 3 | 87, 45, 497, 910 |
| 5 | 29, 15, 497, 910 |
| 7 | 29, 3, 497, 182 |
| 29, 3, 71, 26 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 3 x 5 x 7 x 29 x 3 x 71 x 26 = 151768890
Therefore, the lowest common multiple of 783,405,497,910 is 151768890.
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 405 x 497 x 910 = 143421601050
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
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
497 : 1, 7, 71, 497
910 : 1, 2, 5, 7, 10, 13, 14, 26, 35, 65, 70, 91, 130, 182, 455, 910
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 783,405,497,910, is 1.
Now, the common factors can be found like this.
783:3x 3x 3x 29
405:3x 3x 3x 3x 5
497:7x 71
910:2x 5x 7x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 5x 7 = 945
Therefore, the value for common factors is 945.
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 = 143421601050/(1x945)
LCM = 143421601050/945
LCM = 151768890
Thus, we can understand that the LCM of 783,405,497,910 is 151768890.
