Given numbers are 655,786,227,405
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 655,786,227,405 is 24086970.
Find LCM of 655,786,227,405 with Prime Factorization
| 3 | 655, 786, 227, 405 |
| 5 | 655, 262, 227, 135 |
| 131 | 131, 262, 227, 27 |
| 1, 2, 227, 27 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 131 x 1 x 2 x 227 x 27 = 24086970
Therefore, the lowest common multiple of 655,786,227,405 is 24086970.
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.
655 x 786 x 227 x 405 = 47330896050
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.
655 : 1, 5, 131, 655
786 : 1, 2, 3, 6, 131, 262, 393, 786
227 : 1, 227
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 655,786,227,405, is 1.
Now, the common factors can be found like this.
655:5x 131
786:2x 3x 131
227:227
405:3x 3x 3x 3x 5
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 131 = 1965
Therefore, the value for common factors is 1965.
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 = 47330896050/(1x1965)
LCM = 47330896050/1965
LCM = 24086970
Thus, we can understand that the LCM of 655,786,227,405 is 24086970.
