# What is the HCF of 1.75, 5.6 and 7?

The largest possible number which divides the given numbers exactly without any remainder is called the HCF (Highest Common Factor).

## Answer: The HCF of 1.75, 5.6 and 7 is 0.35

To calculate the HCF of decimal numbers first make the numbers as whole numbers by multiplying all the numbers with the same number.

## Explanation:

Make all the numbers 1.75, 5.6, and 7 as whole numbers by multiplying all the numbers with 100

Therefore the numbers will become; 175, 560 and 700

Now find the prime factors of the numbers; 175, 560 and 700

Prime factorization of 175: 5 × 5 × 7

Prime factorization of 560: 2 × 2 × 2 × 2 × 5 × 7

Prime factorization of 700: 2 × 2 × 5 × 5 × 7

Now the common factors among all the prime factors of 175, 560 and 700 are: 5 and 7

The HCF of 175, 560 and 700 is 5 × 7 = 35

Now the required H.C.F. of 1.75, 5.6 and 7 is: 35/100 = 0.35
