There are 8 prime numbers between 10 and 40: 11 13 17 19 23 29 31 37.
There are 4 prime numbers between 20 and 40.
To find pairs of numbers with a least common multiple (LCM) of 40, we need to consider the prime factorization of 40, which is 2^3 * 5. Any pair of numbers whose prime factorization includes these factors can have a LCM of 40. For example, 8 and 10 have a LCM of 40 because 8 = 2^3 and 10 = 2 * 5. Another pair could be 20 and 40, as both have the prime factors of 40.

TO work out the HCF you need to split the numbers into their prime factors. In this case you have: 40 = 2x2x2x5 48 = 2x2x2x2x3 The next step is to identify any common prime factors. Both numbers have three 2s as prime factors. Multiply these together and you get: 2x2x2 = 8 Thus the HCF of 40 and 48 is 8.
