WebMay 2, 2024 · Get rid of all the 2’s which give even factors in 72, so divide 72 by 2^3=8: 72/2^3=9=3^2. Now, 9 will have all the odd factors of 72 and won’t have its even factors. The number of factors of 9 is (2+1)=3. So, we know that 72 has total of 12 factors out of which 3 are odd. Therefore 72 has 12-3=9 even factors. WebOct 25, 2024 · What are Divisors of 72. A number n is a divisor of 72 if 72 n is an integer. Note that if 72/n=m is an integer, then both m and n will be the divisors of 72. To find the divisors of 72, we need to find the numbers n such that 72/n becomes an integer. We have: 72/1=72. 1, 72 are divisors of 72. 72/2=36. 2, 36 are divisors of 72.
