Given numbers are 9156,4641
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 9156,4641 is 2023476.
Find LCM of 9156,4641 with Prime Factorization
| 3 | 9156, 4641 |
| 7 | 3052, 1547 |
| 436, 221 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 436 x 221 = 2023476
Therefore, the lowest common multiple of 9156,4641 is 2023476.
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.
9156 x 4641 = 42492996
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.
9156 : 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 84, 109, 218, 327, 436, 654, 763, 1308, 1526, 2289, 3052, 4578, 9156
4641 : 1, 3, 7, 13, 17, 21, 39, 51, 91, 119, 221, 273, 357, 663, 1547, 4641
21 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 9156,4641, is 21.
Now, the common factors can be found like this.
9156:2x 2x 3x 7x 109
4641:3x 7x 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 = 42492996/(21x1)
LCM = 42492996/21
LCM = 2023476
Thus, we can understand that the LCM of 9156,4641 is 2023476.
