Question

how to take out the HCF of any number u get in exams

Answer 1

Express the number in terms of its prime factors.

Let’s say for example:
24 and 35

24 = 2x2x2x3
36 = 2x2x3x3

Now you can see,
2x2x3 is common in both.
Thus, 2x2x3 = 12 is the HCF.

Answer 2

HELLO MATE

FIRST EXPRESS THAT NUMBER IN MULTIPLICATION

225-5×5×3×3
30-2×3×5

HCF=5×3(as they are the only common no.s)=15
