Given numbers are 269,231,806,987
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 269,231,806,987 is 2353949598.
Find LCM of 269,231,806,987 with Prime Factorization
| 3 | 269, 231, 806, 987 |
| 7 | 269, 77, 806, 329 |
| 269, 11, 806, 47 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 269 x 11 x 806 x 47 = 2353949598
Therefore, the lowest common multiple of 269,231,806,987 is 2353949598.
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.
269 x 231 x 806 x 987 = 49432941558
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.
269 : 1, 269
231 : 1, 3, 7, 11, 21, 33, 77, 231
806 : 1, 2, 13, 26, 31, 62, 403, 806
987 : 1, 3, 7, 21, 47, 141, 329, 987
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 269,231,806,987, is 1.
Now, the common factors can be found like this.
269:269
231:3x 7x 11
806:2x 13x 31
987:3x 7x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 7 = 21
Therefore, the value for common factors is 21.
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 = 49432941558/(1x21)
LCM = 49432941558/21
LCM = 2353949598
Thus, we can understand that the LCM of 269,231,806,987 is 2353949598.
