40 = 2^3*5.
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.

40 = 23 x 51 60 = 22 x 31 x 51
Prime factorization of 90 = 2x3x3x5
Prime factorization of 40 = 2x2x2x5 Prime factorization of 100 = 2x2x5x5
The prime factorization of 40 is 2x2x2x5 or 23x5.
40
2x2x2x5
Yes, 2x2x2x5 can be written in prime factorization as 2^3 x 5. In prime factorization, we break down a number into its prime factors. Here, 2 is a prime number and appears three times, so we write it as 2^3. The number 5 is also a prime number and appears once, so we simply write 5.
The prime factorization of 32 is 2x2x2x2x2 or 25. The prime factorization of 40 is 2x2x2x5 or 23x5. For a number to be a multiple of a given number the multiple must have the entire prime factorization of that number in is. So a multiple of 32 must contain 2x2x2x2x2 or 25 . Likewise a multiple of 40 must contain 2x2x2x5 or 23x5. The least number that this could possible happen with must have 5 factors of 2 and one factor of 5 (the highest exponent on each individual prime factor). Thus the LCM is 2x2x2x2x2x5 or 25x5 Which is 160.
