Find LCM of 805,540,300,139,243 with Prime Factorization
| 2 | 805, 540, 300, 139, 243 |
| 2 | 805, 270, 150, 139, 243 |
| 3 | 805, 135, 75, 139, 243 |
| 3 | 805, 45, 25, 139, 81 |
| 3 | 805, 15, 25, 139, 27 |
| 5 | 805, 5, 25, 139, 9 |
| 161, 1, 5, 139, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 3 x 5 x 161 x 1 x 5 x 139 x 9 = 543809700
Therefore, the lowest common multiple of 805,540,300,139,243 is 543809700.
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.
805 x 540 x 300 x 139 x 243 = 4404858570000
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.
805 : 1, 5, 7, 23, 35, 115, 161, 805
540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540
300 : 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 25, 30, 50, 60, 75, 100, 150, 300
139 : 1, 139
243 : 1, 3, 9, 27, 81, 243
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 805,540,300,139,243, is 1.
Now, the common factors can be found like this.
805:5x 7x 23
540:2x 2x 3x 3x 3x 5
300:2x 2x 3x 5x 5
139:139
243:3x 3x 3x 3x 3
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 3x 3x 3x 3x 5x 5 = 8100
Therefore, the value for common factors is 8100.
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 = 4404858570000/(1x8100)
LCM = 4404858570000/8100
LCM = 543809700
Thus, we can understand that the LCM of 805,540,300,139,243 is 543809700.
