2 and 40 4 and 10
The least common multiple is the smallest number that is multiple of two or more numbers. 24: 48, 72, 96, 120 40: 40, 80, 120 The LCM for 24 and 40 is 120.
If the numbers are x and y then x + y = 40 x - y = 10 so x = 25, y = 15 Then LCM(x, y) = LCM(25, 15) = 75
The HCF is always a factor of the LCM of two numbers. The HCF is a factor of both the numbers which are factors of their LCM. Thus the HCF is also a factor of the LCM of the two numbers.
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.
You need at least two numbers to find an LCM.
