Find LCM of 851,999,663,459 with Prime Factorization
| 3 | 851, 999, 663, 459 |
| 3 | 851, 333, 221, 153 |
| 3 | 851, 111, 221, 51 |
| 17 | 851, 37, 221, 17 |
| 37 | 851, 37, 13, 1 |
| 23, 1, 13, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 3 x 17 x 37 x 23 x 1 x 13 x 1 = 5077917
Therefore, the lowest common multiple of 851,999,663,459 is 5077917.
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.
851 x 999 x 663 x 459 = 258714793233
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.
851 : 1, 23, 37, 851
999 : 1, 3, 9, 27, 37, 111, 333, 999
663 : 1, 3, 13, 17, 39, 51, 221, 663
459 : 1, 3, 9, 17, 27, 51, 153, 459
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 851,999,663,459, is 1.
Now, the common factors can be found like this.
851:23x 37
999:3x 3x 3x 37
663:3x 13x 17
459:3x 3x 3x 17
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 3x 17x 37 = 50949
Therefore, the value for common factors is 50949.
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 = 258714793233/(1x50949)
LCM = 258714793233/50949
LCM = 5077917
Thus, we can understand that the LCM of 851,999,663,459 is 5077917.
