Question

Find
H.CF of 25 and 85​

Answer 1

Answer:

5

Step-by-step explanation:

25 = 5*5

85 = 5*17

highest common factor = 5

Answer 2

Step-by-step explanation:

We can find H.C.F by 2 methods:-

1st method

$\huge\mathcal\pink{Prime \: factorisation}$

=>25=5×5

=>85=5×17

take out the common factors, here it is 5.

So, the H.C.F is 5

2nd method

$\large\mathcal\pink{Euclid's \: division \: lemma}$

Divide 85/25

=> the result can be written as:-85=25×3+10

Divide 25/10

=> the result can be written as:-25=10×2+5

so, the last term will be the H.C.F

here, it is 5
