Find LCM of 261,486,675,805,743 with Prime Factorization
| 3 | 261, 486, 675, 805, 743 |
| 3 | 87, 162, 225, 805, 743 |
| 3 | 29, 54, 75, 805, 743 |
| 5 | 29, 18, 25, 805, 743 |
| 29, 18, 5, 161, 743 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 3 x 5 x 29 x 18 x 5 x 161 x 743 = 42149164050
Therefore, the lowest common multiple of 261,486,675,805,743 is 42149164050.
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.
261 x 486 x 675 x 805 x 743 = 51211234320750
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.
261 : 1, 3, 9, 29, 87, 261
486 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162, 243, 486
675 : 1, 3, 5, 9, 15, 25, 27, 45, 75, 135, 225, 675
805 : 1, 5, 7, 23, 35, 115, 161, 805
743 : 1, 743
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 261,486,675,805,743, is 1.
Now, the common factors can be found like this.
261:3x 3x 29
486:2x 3x 3x 3x 3x 3
675:3x 3x 3x 5x 5
805:5x 7x 23
743:743
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 3x 5 = 1215
Therefore, the value for common factors is 1215.
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 = 51211234320750/(1x1215)
LCM = 51211234320750/1215
LCM = 42149164050
Thus, we can understand that the LCM of 261,486,675,805,743 is 42149164050.
