Given numbers are 1305,3213
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 1305,3213 is 465885.
Find LCM of 1305,3213 with Prime Factorization
| 3 | 1305, 3213 |
| 3 | 435, 1071 |
| 145, 357 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 145 x 357 = 465885
Therefore, the lowest common multiple of 1305,3213 is 465885.
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.
1305 x 3213 = 4192965
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.
1305 : 1, 3, 5, 9, 15, 29, 45, 87, 145, 261, 435, 1305
3213 : 1, 3, 7, 9, 17, 21, 27, 51, 63, 119, 153, 189, 357, 459, 1071, 3213
9 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 1305,3213, is 9.
Now, the common factors can be found like this.
1305:3x 3x 5x 29
3213:3x 3x 3x 7x 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 = 4192965/(9x1)
LCM = 4192965/9
LCM = 465885
Thus, we can understand that the LCM of 1305,3213 is 465885.
