Question

2. Find the H.C.F. of the following numbers using long division method:

(vii) $112,140,168$

Answer 1

Using the long division method,

Divide $140by112$

$1121140-11228$

$140=112\times 1+28$

Now divide $112by28$

$284112-1120$

$112=28\times 4+0$

Now divide $168by28$

$286168-1680$

$168=28\times 6+0$

The remainder is $0$, So $28$ is the H.C.F. of $112,140,168$.
