The LCM of 786,751,486,999 is 1769087142.
Find LCM of 786,751,486,999 with Prime Factorization
| 2 | 786, 751, 486, 999 |
| 3 | 393, 751, 243, 999 |
| 3 | 131, 751, 81, 333 |
| 3 | 131, 751, 27, 111 |
| 131, 751, 9, 37 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 131 x 751 x 9 x 37 = 1769087142
Therefore, the lowest common multiple of 786,751,486,999 is 1769087142.
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.
786 x 751 x 486 x 999 = 286592117004
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.
786 : 1, 2, 3, 6, 131, 262, 393, 786
751 : 1, 751
486 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162, 243, 486
999 : 1, 3, 9, 27, 37, 111, 333, 999
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 786,751,486,999, is 1.
Now, the common factors can be found like this.
786:2x 3x 131
751:751
486:2x 3x 3x 3x 3x 3
999:3x 3x 3x 37
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 3 = 162
Therefore, the value for common factors is 162.
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 = 286592117004/(1x162)
LCM = 286592117004/162
LCM = 1769087142
Thus, we can understand that the LCM of 786,751,486,999 is 1769087142.
