12

Answer 2

Answer:

HCF of 63 90 and 36 is 9.

Step-by-step explanation:

Given three numbers are 63,90,36.

First we need to break all numbers into prime numbers.

$63 = 3 \times 3 \times 7$

$90 = 3 \times 3 \times 2 \times 5$

$36 = 3 \times 3 \times 2 \times 2$

HCF means Highest Common Factor.

Let two numbers be ${x}^{2} y$and ${y}^{2} x$

For finding HCF of this number first we will breack these terms into prime numbers.

${x}^{2} y = x \times x \times y \\ and \: {y}^{2} x = y \times y \times x$

HCF of ${x}^{2} y$and ${y}^{2} x$is $x \times y = xy$

Similarly HCF of given numbers is $3 \times 3 = 9$.
