Given numbers are 306,518,198,731
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 306,518,198,731 is 37487142.
Find LCM of 306,518,198,731 with Prime Factorization
| 2 | 306, 518, 198, 731 |
| 3 | 153, 259, 99, 731 |
| 3 | 51, 259, 33, 731 |
| 17 | 17, 259, 11, 731 |
| 1, 259, 11, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 17 x 1 x 259 x 11 x 43 = 37487142
Therefore, the lowest common multiple of 306,518,198,731 is 37487142.
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.
306 x 518 x 198 x 731 = 22942130904
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.
306 : 1, 2, 3, 6, 9, 17, 18, 34, 51, 102, 153, 306
518 : 1, 2, 7, 14, 37, 74, 259, 518
198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198
731 : 1, 17, 43, 731
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 306,518,198,731, is 1.
Now, the common factors can be found like this.
306:2x 3x 3x 17
518:2x 7x 37
198:2x 3x 3x 11
731:17x 43
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 3x 3x 17 = 612
Therefore, the value for common factors is 612.
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 = 22942130904/(1x612)
LCM = 22942130904/612
LCM = 37487142
Thus, we can understand that the LCM of 306,518,198,731 is 37487142.
