Question

If a equals to 2 square into three cube into five race to 4 and b equals to 2 cube into three square into five then find the hcf of a, b

Answer 1

Answer: 180

Step-by-step explanation:

$a = 2^2*3^3*5^4\\b=2^3*3^2*5$

choose the minimum power of each number 2,3 and 5.

For 2 :   $2^2$

For 3:    $3^2$

For 5:    $5^1$

Now, multiply them:

HCF = $2^2*3^2*5^1$

HCF = $4*9*5$

HCF = 180
