Find the LCM of 51, 17, 13, 65 with the LCM of Two or More Numbers Calculator. Here we are teaching you two different methods through which you can calculate the LCM of 51, 17, 13, 65. So, keep reading to learn more.
Given numbers are 51,17,13,65
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 51,17,13,65 is 3315.
Find LCM of 51,17,13,65 with Prime Factorization
13 | 51, 17, 13, 65 |
17 | 51, 17, 1, 5 |
3, 1, 1, 5 |
Multiply the prime numbers at the bottom and the left side.
13 x 17 x 3 x 1 x 1 x 5 = 3315
Therefore, the lowest common multiple of 51,17,13,65 is 3315.
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.
51 x 17 x 13 x 65 = 732615
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.
51 : 1, 3, 17, 51
17 : 1, 17
13 : 1, 13
65 : 1, 5, 13, 65
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 51,17,13,65, is 1.
Now, the common factors can be found like this.
51:3x 17
17:17
13:13
65:5x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13x 17 = 221
Therefore, the value for common factors is 221.
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 = 732615/(1x221)
LCM = 732615/221
LCM = 3315
Thus, we can understand that the LCM of 51,17,13,65 is 3315.
