Given numbers are 540,235,798,687,687
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 540,235,798,687,687 is 772998660.
Find LCM of 540,235,798,687,687 with Prime Factorization
| 2 | 540, 235, 798, 687, 687 |
| 3 | 270, 235, 399, 687, 687 |
| 5 | 90, 235, 133, 229, 229 |
| 229 | 18, 47, 133, 229, 229 |
| 18, 47, 133, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 229 x 18 x 47 x 133 x 1 x 1 = 772998660
Therefore, the lowest common multiple of 540,235,798,687,687 is 772998660.
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.
540 x 235 x 798 x 687 x 687 = 47794507147800
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.
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
235 : 1, 5, 47, 235
798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798
687 : 1, 3, 229, 687
687 : 1, 3, 229, 687
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 540,235,798,687,687, is 1.
Now, the common factors can be found like this.
540:2x 2x 3x 3x 3x 5
235:5x 47
798:2x 3x 7x 19
687:3x 229
687:3x 229
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 5x 229 = 61830
Therefore, the value for common factors is 61830.
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 = 47794507147800/(1x61830)
LCM = 47794507147800/61830
LCM = 772998660
Thus, we can understand that the LCM of 540,235,798,687,687 is 772998660.
