Given numbers are 241,655,308,660
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 241,655,308,660 is 145858020.
Find LCM of 241,655,308,660 with Prime Factorization
| 2 | 241, 655, 308, 660 |
| 2 | 241, 655, 154, 330 |
| 5 | 241, 655, 77, 165 |
| 11 | 241, 131, 77, 33 |
| 241, 131, 7, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 11 x 241 x 131 x 7 x 3 = 145858020
Therefore, the lowest common multiple of 241,655,308,660 is 145858020.
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.
241 x 655 x 308 x 660 = 32088764400
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.
241 : 1, 241
655 : 1, 5, 131, 655
308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308
660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 241,655,308,660, is 1.
Now, the common factors can be found like this.
241:241
655:5x 131
308:2x 2x 7x 11
660:2x 2x 3x 5x 11
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 5x 11 = 220
Therefore, the value for common factors is 220.
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 = 32088764400/(1x220)
LCM = 32088764400/220
LCM = 145858020
Thus, we can understand that the LCM of 241,655,308,660 is 145858020.
