Given numbers are 282,231,517,138
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 282,231,517,138 is 499422.
Find LCM of 282,231,517,138 with Prime Factorization
| 2 | 282, 231, 517, 138 |
| 3 | 141, 231, 517, 69 |
| 11 | 47, 77, 517, 23 |
| 47 | 47, 7, 47, 23 |
| 1, 7, 1, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 47 x 1 x 7 x 1 x 23 = 499422
Therefore, the lowest common multiple of 282,231,517,138 is 499422.
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.
282 x 231 x 517 x 138 = 4647621132
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.
282 : 1, 2, 3, 6, 47, 94, 141, 282
231 : 1, 3, 7, 11, 21, 33, 77, 231
517 : 1, 11, 47, 517
138 : 1, 2, 3, 6, 23, 46, 69, 138
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 282,231,517,138, is 1.
Now, the common factors can be found like this.
282:2x 3x 47
231:3x 7x 11
517:11x 47
138:2x 3x 23
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 47 = 9306
Therefore, the value for common factors is 9306.
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 = 4647621132/(1x9306)
LCM = 4647621132/9306
LCM = 499422
Thus, we can understand that the LCM of 282,231,517,138 is 499422.
