Given numbers are 711,135,669,242,105
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 711,135,669,242,105 is 4028831730.
Find LCM of 711,135,669,242,105 with Prime Factorization
| 3 | 711, 135, 669, 242, 105 |
| 3 | 237, 45, 223, 242, 35 |
| 5 | 79, 15, 223, 242, 35 |
| 79, 3, 223, 242, 7 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 79 x 3 x 223 x 242 x 7 = 4028831730
Therefore, the lowest common multiple of 711,135,669,242,105 is 4028831730.
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.
711 x 135 x 669 x 242 x 105 = 1631676850650
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.
711 : 1, 3, 9, 79, 237, 711
135 : 1, 3, 5, 9, 15, 27, 45, 135
669 : 1, 3, 223, 669
242 : 1, 2, 11, 22, 121, 242
105 : 1, 3, 5, 7, 15, 21, 35, 105
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 711,135,669,242,105, is 1.
Now, the common factors can be found like this.
711:3x 3x 79
135:3x 3x 3x 5
669:3x 223
242:2x 11x 11
105:3x 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 3x 5 = 405
Therefore, the value for common factors is 405.
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 = 1631676850650/(1x405)
LCM = 1631676850650/405
LCM = 4028831730
Thus, we can understand that the LCM of 711,135,669,242,105 is 4028831730.
