Given numbers are 243,762,918,760
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 243,762,918,760 is 398724120.
Find LCM of 243,762,918,760 with Prime Factorization
| 2 | 243, 762, 918, 760 |
| 3 | 243, 381, 459, 380 |
| 3 | 81, 127, 153, 380 |
| 3 | 27, 127, 51, 380 |
| 9, 127, 17, 380 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 9 x 127 x 17 x 380 = 398724120
Therefore, the lowest common multiple of 243,762,918,760 is 398724120.
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.
243 x 762 x 918 x 760 = 129186614880
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.
243 : 1, 3, 9, 27, 81, 243
762 : 1, 2, 3, 6, 127, 254, 381, 762
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
760 : 1, 2, 4, 5, 8, 10, 19, 20, 38, 40, 76, 95, 152, 190, 380, 760
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 243,762,918,760, is 1.
Now, the common factors can be found like this.
243:3x 3x 3x 3x 3
762:2x 3x 127
918:2x 3x 3x 3x 17
760:2x 2x 2x 5x 19
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 3 = 324
Therefore, the value for common factors is 324.
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 = 129186614880/(1x324)
LCM = 129186614880/324
LCM = 398724120
Thus, we can understand that the LCM of 243,762,918,760 is 398724120.
