# HOW TO FIND HCF OF TWO NUMBERS IN DECIMAL

## About "How to find hcf of two numbers in decimal"

How to find hcf of two numbers in decimal :

We know that different numbers have common divisors. Among the common divisors the greatest divisor is the highest common factor (hcf)

To find the hcf of the decimal numbers, we have to follow the steps given below.

Step 1 :

If necessary, make the same number of decimal places in all the given numbers.

Step 2 :

Find their hcf as if they were integers

Step 3 :

Mark in the result as many decimal places as there are in each of the numbers.

Question 1 :

Find the highest common factor of 0.90 and 0.30

Solution :

To find the highest common factors of 0.90 and 0.30, first we have to multiply each decimal number by 100.

0.90 x 100  =  90

0.30 x 100  =  30

H.C.F of 90 and 30  =  30

Divide the hcf (30) by 100.

H.C.F of 0.90 and 0.30  =  30/100  =  0.30

Question 2 :

Find the highest common factor of 0.36 and 0.27

Solution :

To find the highest common factors of 0.36 and 0.27, first we have to multiply each decimal number by 100.

0.36 x 100  =  36

0.27 x 100  =  27

H.C.F of 36 and 27  =  9

Divide the hcf (9) by 100.

H.C.F of 0.36 and 0.27  =  9/100  =  0.90

Question 3 :

Find the highest common factor of 75 and 45.

Solution :

To find the highest common factors of 0.75 and 0.45, first we have to multiply each decimal number by 100.

0.75 x 100  =  75

0.45 x 100  =  45

H.C.F of 75 and 45  =  15

Divide the hcf (15) by 100.

H.C.F of 0.75 and 0.45  =  15/100  =  0.15

Question 4 :

Find the highest common factor of 36 and 72.

Solution :

To find the highest common factors of 0.36 and 0.72, first we have to multiply each decimal number by 100.

0.36 x 100  =  36

0.72 x 100  =  72

H.C.F of 36 and 72  =  12

Divide the hcf (12) by 100.

H.C.F of 0.36 and 0.72  =  12/100  =  0.12

Question 5 :

Find the highest common factor of 72 and 63.

Solution :

To find the highest common factors of 0.72 and 0.63, first we have to multiply each decimal number by 100.

0.72 x 100  =  72

0.63 x 100  =  63

H.C.F of 72 and 63  =  9

Divide the hcf (9) by 100.

H.C.F of 0.72 and 0.63  =  9/100  =  0.09
