Find the HCF of 24, 32 and 36 ?
Answers
Step-by-step explanation:
HCF of 24, 32, 36 =2*2*2*2*2*3*3
=32 *9
=288
Step-by-step explanation:
The instructions to find the GCF of 24, 32, 36 and 80 are the next:
1. Decompose all numbers into prime factors
24 2 12 2 6 2 3 3 1 32 2 16 2 8 2 4 2 2 2 1 36 2 18 2 9 3 3 3 1 80 2 40 2 20 2 10 2 5 5 1
2. Write all numbers as the product of its prime factors
Prime factors of 24 = 23 . 3
Prime factors of 32 = 25
Prime factors of 36 = 22 . 32
Prime factors of 80 = 24 . 5
3. Choose the common prime factors with the lowest exponent
Common prime factors: 2
Common prime factors with the lowest exponent: 22
4. Calculate the Greatest Common Factor or GCF
Remember, to find the GCF of several numbers you must multiply the common prime factors with the lowest exponent.
GCF = 22 = 4
