Answer 2

Answer:

If you are in 10th std. please follow 1st trick and if you are in lower class then follow 2nd trick.

Step-by-step explanation:

1] By Euclid's division lemma:

according to Euclid's division lemma,

dividend=divisor×quotient+remainder.

here, dividend = 24

divisor=12

so,

24=12×2+0

here, if remainder is zero then the divisor is the answer. if remainder is not zero then the divisor becomes dividend and the process continues till the remainder is zero.

in this, the remainder is zero so H.C.F (12,24)= 12 i.e the divisor.

2] By Prime Factorisation Method:

First of all, we need to find out factors of 12 and 24 separately which is shown below:

12= 2×2×3

24=2×2×2×3

now, select the factors that are present in both numbers..

here it is 2,2,3

now multiply all the common factors and get the answer as shown below:

2×2×3=12

so HCF of 24&12 is 12..
