The LCM of these numbers is 140.
The variance of 14 14 20 38 47 48 57 = 317.6667
It is 14 and 6.
I really think you can do this. 13, 14, 15, 16, 17, 18, 19, 20...
11 and 8
14=14 and 20=20 All numbers have different values, and the only number equal to itself is itself.
The easiest way to do this is to split the numbers down into their prime factors: 14 = 2x7 20 = 2x2x5 The next step is to spot any common prime factors. In this case both numbers have a 2 as a prime factor. Therefore, the HCF of 14 and 20 is 2.
The least common multiple of the numbers 14, 20 and 22 is 1,540.
The LCM of these numbers is 140.
14+6=20 and6-14=8
The variance of 14 14 20 38 47 48 57 = 317.6667
It is 14 and 6.
The composite numbers between 10 and 20 are 12, 14, 15, 16 and 18.
2 and 4 are common multiples of the numbers 14 and 20
It is 20*(14-12)+7-6 = 41
I really think you can do this. 13, 14, 15, 16, 17, 18, 19, 20...
