Given numbers are 1620,9664
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 1620,9664 is 3913920.
Find LCM of 1620,9664 with Prime Factorization
| 2 | 1620, 9664 |
| 2 | 810, 4832 |
| 405, 2416 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 405 x 2416 = 3913920
Therefore, the lowest common multiple of 1620,9664 is 3913920.
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.
1620 x 9664 = 15655680
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.
1620 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 81, 90, 108, 135, 162, 180, 270, 324, 405, 540, 810, 1620
9664 : 1, 2, 4, 8, 16, 32, 64, 151, 302, 604, 1208, 2416, 4832, 9664
4 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 1620,9664, is 4.
Now, the common factors can be found like this.
1620:2x 2x 3x 3x 3x 3x 5
9664:2x 2x 2x 2x 2x 2x 151
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 = 15655680/(4x1)
LCM = 15655680/4
LCM = 3913920
Thus, we can understand that the LCM of 1620,9664 is 3913920.
