Given numbers are 605,206,622,103
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 605,206,622,103 is 38759930.
Find LCM of 605,206,622,103 with Prime Factorization
| 2 | 605, 206, 622, 103 |
| 103 | 605, 103, 311, 103 |
| 605, 1, 311, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 103 x 605 x 1 x 311 x 1 = 38759930
Therefore, the lowest common multiple of 605,206,622,103 is 38759930.
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.
605 x 206 x 622 x 103 = 7984545580
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.
605 : 1, 5, 11, 55, 121, 605
206 : 1, 2, 103, 206
622 : 1, 2, 311, 622
103 : 1, 103
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 605,206,622,103, is 1.
Now, the common factors can be found like this.
605:5x 11x 11
206:2x 103
622:2x 311
103:103
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 103 = 206
Therefore, the value for common factors is 206.
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 = 7984545580/(1x206)
LCM = 7984545580/206
LCM = 38759930
Thus, we can understand that the LCM of 605,206,622,103 is 38759930.
