Answer 1

$\displaystyle\huge\red{\underline{\underline{Solution}}}$

TO DETERMINE

The HCF of 70 , 115 , 175

CONCEPT TO BE IMPLEMENTED

HCF : The HCF of three given numbers is the greatest integer which divides each of the given numbers

PROCESS :

( Using Prime Factorisation )

STEP : 1 Prime factorise the given numbers

STEP : 2 Search of greatest integer which divides each of the given numbers

STEP : 3 The obtained number is the required HCF

CALCULATION

The given three numbers are 70 , 115 , 175

$\sf{ 70 = 2\times 5 \times 7\: }$

$\sf{115 = 5 \times 23 \: }$

$\sf{175 = 5 \times 5 \times 7 \: }$

Since 5 is the greatest integer which divides each of the given numbers

Hence the HCF of 70 , 115 , 175 = 5

Answer 2

The Highest common factors of 70, 105, and 175:

The highest common factor or HCF of 70, 105, 175 by using the constant division process is 35.

• HCF of two numbers is the highest common factor of 2 numbers.

• Finding HCF

               105) 175 (1

                       105

                         70)105(1

                                70

                                 35)70(2

                                       70

                                         0

Therefore,  The HCF of 70, 105, 175 by using the continued division technique is 35.
