Find LCM of 231,730,197,861,242 with Prime Factorization
| 2 | 231, 730, 197, 861, 242 |
| 3 | 231, 365, 197, 861, 121 |
| 7 | 77, 365, 197, 287, 121 |
| 11 | 11, 365, 197, 41, 121 |
| 1, 365, 197, 41, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 11 x 1 x 365 x 197 x 41 x 11 = 14982269610
Therefore, the lowest common multiple of 231,730,197,861,242 is 14982269610.
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.
231 x 730 x 197 x 861 x 242 = 6921808559820
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.
231 : 1, 3, 7, 11, 21, 33, 77, 231
730 : 1, 2, 5, 10, 73, 146, 365, 730
197 : 1, 197
861 : 1, 3, 7, 21, 41, 123, 287, 861
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 231,730,197,861,242, is 1.
Now, the common factors can be found like this.
231:3x 7x 11
730:2x 5x 73
197:197
861:3x 7x 41
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 3x 7x 11 = 462
Therefore, the value for common factors is 462.
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 = 6921808559820/(1x462)
LCM = 6921808559820/462
LCM = 14982269610
Thus, we can understand that the LCM of 231,730,197,861,242 is 14982269610.
