Given numbers are 198,786,759,231
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 198,786,759,231 is 4176018.
Find LCM of 198,786,759,231 with Prime Factorization
| 2 | 198, 786, 759, 231 |
| 3 | 99, 393, 759, 231 |
| 11 | 33, 131, 253, 77 |
| 3, 131, 23, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 3 x 131 x 23 x 7 = 4176018
Therefore, the lowest common multiple of 198,786,759,231 is 4176018.
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.
198 x 786 x 759 x 231 = 27286101612
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.
198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198
786 : 1, 2, 3, 6, 131, 262, 393, 786
759 : 1, 3, 11, 23, 33, 69, 253, 759
231 : 1, 3, 7, 11, 21, 33, 77, 231
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 198,786,759,231, is 3.
Now, the common factors can be found like this.
198:2x 3x 3x 11
786:2x 3x 131
759:3x 11x 23
231:3x 7x 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 3x 11x 11 = 2178
Therefore, the value for common factors is 2178.
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 = 27286101612/(3x2178)
LCM = 27286101612/6534
LCM = 4176018
Thus, we can understand that the LCM of 198,786,759,231 is 4176018.
