LCM with prime factorization of 32 and 40?
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.

Yes, the prime factorization of 40 is 2 x 2 x 2 x 5
What is the lowest common multipule between 10 and 8?
Prime factor both then use the factors the number of times it was used the most in either one. 10=2x5 8=2x2x2 2x2x2x5=40
What number goes into 25 and 40?
25=5x5 40=2x2x2x5 5 is the common factor
What the HCF of 25 and 40?
To work this out, you have to split the numbers into the product of their prime factors: 25 = 5x5 40 = 2x2x2x5 The next step is to identify any common factors. In this case, both numbers have a 5 as a prime factor. Thus the HCF of 25 and 40 is 5.
What is the LCM of 40 12?
I factor each and then use each prime factor the most it was used in either number. 40=2x2x2x5 12=2x2x3 LCM=2x2x2x3x5=120 You can also write out the multiples of each until you have one that is in both lists. 12,24,36,48,60,72,84,96,108,120 40,80,120
