Given numbers are 7842,3138
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 7842,3138 is 4101366.
Find LCM of 7842,3138 with Prime Factorization
| 2 | 7842, 3138 |
| 3 | 3921, 1569 |
| 1307, 523 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 1307 x 523 = 4101366
Therefore, the lowest common multiple of 7842,3138 is 4101366.
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.
7842 x 3138 = 24608196
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.
7842 : 1, 2, 3, 6, 1307, 2614, 3921, 7842
3138 : 1, 2, 3, 6, 523, 1046, 1569, 3138
6 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 7842,3138, is 6.
Now, the common factors can be found like this.
7842:2x 3x 1307
3138:2x 3x 523
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 = 24608196/(6x1)
LCM = 24608196/6
LCM = 4101366
Thus, we can understand that the LCM of 7842,3138 is 4101366.
