Given numbers are 3478,7986
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 3478,7986 is 13887654.
Find LCM of 3478,7986 with Prime Factorization
| 2 | 3478, 7986 |
| 1739, 3993 |
Multiply the prime numbers at the bottom and the left side.
2 x 1739 x 3993 = 13887654
Therefore, the lowest common multiple of 3478,7986 is 13887654.
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.
3478 x 7986 = 27775308
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.
3478 : 1, 2, 37, 47, 74, 94, 1739, 3478
7986 : 1, 2, 3, 6, 11, 22, 33, 66, 121, 242, 363, 726, 1331, 2662, 3993, 7986
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 3478,7986, is 2.
Now, the common factors can be found like this.
3478:2x 37x 47
7986:2x 3x 11x 11x 11
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 = 27775308/(2x1)
LCM = 27775308/2
LCM = 13887654
Thus, we can understand that the LCM of 3478,7986 is 13887654.
