The prime factors of 25 are 5x5.
The prime factors of 40 are 2x2x2x5.
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.
They are: 29 31 and 37
It can be. 40 is relatively prime to 41. 40 is not relatively prime to 54.

21 = 3x7 23 = prime 25 = 5x5 27 = 3x9 29 = prime 31 = prime 33 = 3x11 35 = 5x7 37 = prime 39 = 3x13

You multiply 25 by .40 to get 40% of 25. 25*.40=10
Divide both by the same common factor. Repeated division until the numerator and denominator are relatively prime. 625/25 = 25 1000/25 = 40 25/5 = 5 40/5 = 8 answer, 5/8
25 is relatively prime with 36. 25 is not relatively prime with 35.
32 and 25
1, 2, 4, 5, 8, 10, 20 and 40 are the prime factors of 40
5 prime, 25 composite.
