Given numbers are 3924,4047
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 3924,4047 is 5293476.
Find LCM of 3924,4047 with Prime Factorization
| 3 | 3924, 4047 |
| 1308, 1349 |
Multiply the prime numbers at the bottom and the left side.
3 x 1308 x 1349 = 5293476
Therefore, the lowest common multiple of 3924,4047 is 5293476.
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 4047 = 15880428
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
4047 : 1, 3, 19, 57, 71, 213, 1349, 4047
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 3924,4047, is 3.
Now, the common factors can be found like this.
3924:2x 2x 3x 3x 109
4047:3x 19x 71
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 = 15880428/(3x1)
LCM = 15880428/3
LCM = 5293476
Thus, we can understand that the LCM of 3924,4047 is 5293476.
