To find the HCF of two numbers steps are:-

Suppose we have to find the HCF of 18 & 27.

FIRST STEP :- Factorise both number.
18 = 2×3×3
27 = 3×3×3

SECOND TERM:- Write all the terms which is common in both.

HCF(18 & 27) = 3×3

THIRD STEP:- Simplify.
HCF(18 & 27) = 9

So the HCF of 18 & 27 is 9.

Hope u understand.

AnandRoy1: I not understand the third step
Duro84: In third step I just simply solve the second step
Duro84: second step was 3×3
Duro84: So I solved it in 3rd step = 9

→there are two ways to finding HCF of the given number.

★ Prime Factorisation Method

in this method , the factors of numbers should be prime.

for eg: factor of 12 → 2 x 3 x 2, and 8→ 2 x 2 x 2

→ so their HCF is 2 x 2 = 4

★ Euclid division algorithm

in this method u have to do long division method , at end if remainder comes zero, then the last divisor would be considered the HCF.
