Given numbers are 312,471,686,242
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 312,471,686,242 is 2032982952.
Find LCM of 312,471,686,242 with Prime Factorization
| 2 | 312, 471, 686, 242 |
| 3 | 156, 471, 343, 121 |
| 52, 157, 343, 121 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 52 x 157 x 343 x 121 = 2032982952
Therefore, the lowest common multiple of 312,471,686,242 is 2032982952.
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.
312 x 471 x 686 x 242 = 24395795424
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.
312 : 1, 2, 3, 4, 6, 8, 12, 13, 24, 26, 39, 52, 78, 104, 156, 312
471 : 1, 3, 157, 471
686 : 1, 2, 7, 14, 49, 98, 343, 686
242 : 1, 2, 11, 22, 121, 242
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 312,471,686,242, is 1.
Now, the common factors can be found like this.
312:2x 2x 2x 3x 13
471:3x 157
686:2x 7x 7x 7
242:2x 11x 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 3 = 12
Therefore, the value for common factors is 12.
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 = 24395795424/(1x12)
LCM = 24395795424/12
LCM = 2032982952
Thus, we can understand that the LCM of 312,471,686,242 is 2032982952.
