Given numbers are 3924,3992
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 3924,3992 is 3916152.
Find LCM of 3924,3992 with Prime Factorization
| 2 | 3924, 3992 |
| 2 | 1962, 1996 |
| 981, 998 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 981 x 998 = 3916152
Therefore, the lowest common multiple of 3924,3992 is 3916152.
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.
3924 x 3992 = 15664608
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.
3924 : 1, 2, 3, 4, 6, 9, 12, 18, 36, 109, 218, 327, 436, 654, 981, 1308, 1962, 3924
3992 : 1, 2, 4, 8, 499, 998, 1996, 3992
4 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 3924,3992, is 4.
Now, the common factors can be found like this.
3924:2x 2x 3x 3x 109
3992:2x 2x 2x 499
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
= 1
Therefore, the value for common factors is 1.
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 = 15664608/(4x1)
LCM = 15664608/4
LCM = 3916152
Thus, we can understand that the LCM of 3924,3992 is 3916152.
