Given numbers are 9789,7956
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 9789,7956 is 1996956.
Find LCM of 9789,7956 with Prime Factorization
| 3 | 9789, 7956 |
| 13 | 3263, 2652 |
| 251, 204 |
Multiply the prime numbers at the bottom and the left side.
3 x 13 x 251 x 204 = 1996956
Therefore, the lowest common multiple of 9789,7956 is 1996956.
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.
9789 x 7956 = 77881284
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.
9789 : 1, 3, 13, 39, 251, 753, 3263, 9789
7956 : 1, 2, 3, 4, 6, 9, 12, 13, 17, 18, 26, 34, 36, 39, 51, 52, 68, 78, 102, 117, 153, 156, 204, 221, 234, 306, 442, 468, 612, 663, 884, 1326, 1989, 2652, 3978, 7956
39 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 9789,7956, is 39.
Now, the common factors can be found like this.
9789:3x 13x 251
7956:2x 2x 3x 3x 13x 17
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 = 77881284/(39x1)
LCM = 77881284/39
LCM = 1996956
Thus, we can understand that the LCM of 9789,7956 is 1996956.
