The LCM of 72,34,66,18,264 is 13464.
Find LCM of 72,34,66,18,264 with Prime Factorization
2 | 72, 34, 66, 18, 264 |
2 | 36, 17, 33, 9, 132 |
2 | 18, 17, 33, 9, 66 |
3 | 9, 17, 33, 9, 33 |
3 | 3, 17, 11, 3, 11 |
11 | 1, 17, 11, 1, 11 |
1, 17, 1, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 3 x 11 x 1 x 17 x 1 x 1 x 1 = 13464
Therefore, the lowest common multiple of 72,34,66,18,264 is 13464.
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.
72 x 34 x 66 x 18 x 264 = 767771136
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.
72 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72
34 : 1, 2, 17, 34
66 : 1, 2, 3, 6, 11, 22, 33, 66
18 : 1, 2, 3, 6, 9, 18
264 : 1, 2, 3, 4, 6, 8, 11, 12, 22, 24, 33, 44, 66, 88, 132, 264
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 72,34,66,18,264, is 2.
Now, the common factors can be found like this.
72:2x 2x 2x 3x 3
34:2x 17
66:2x 3x 11
18:2x 3x 3
264:2x 2x 2x 3x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 2x 2x 3x 3x 3x 3x 11 = 28512
Therefore, the value for common factors is 28512.
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 = 767771136/(2x28512)
LCM = 767771136/57024
LCM = 13464
Thus, we can understand that the LCM of 72,34,66,18,264 is 13464.
