Given numbers are 261,135,141,517,140
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 261,135,141,517,140 is 56673540.
Find LCM of 261,135,141,517,140 with Prime Factorization
| 3 | 261, 135, 141, 517, 140 |
| 3 | 87, 45, 47, 517, 140 |
| 5 | 29, 15, 47, 517, 140 |
| 47 | 29, 3, 47, 517, 28 |
| 29, 3, 1, 11, 28 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 47 x 29 x 3 x 1 x 11 x 28 = 56673540
Therefore, the lowest common multiple of 261,135,141,517,140 is 56673540.
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 135 x 141 x 517 x 140 = 359593611300
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
135 : 1, 3, 5, 9, 15, 27, 45, 135
141 : 1, 3, 47, 141
517 : 1, 11, 47, 517
140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 261,135,141,517,140, is 1.
Now, the common factors can be found like this.
261:3x 3x 29
135:3x 3x 3x 5
141:3x 47
517:11x 47
140:2x 2x 5x 7
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 47 = 6345
Therefore, the value for common factors is 6345.
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 = 359593611300/(1x6345)
LCM = 359593611300/6345
LCM = 56673540
Thus, we can understand that the LCM of 261,135,141,517,140 is 56673540.
