Question

if hcf of 35 and 45 is 5 ,lcm of 35 and 45 is 63×a then find the value of a .

Answer 1

we know that,

HCF × lcm = product of two numbers

5×63×a = 35×45

a =

$\frac{35 \times 45}{5 \times 63 } = 5$

Answer 2

Concept

The product of the two number is equal to the product of HCF and LCM

Given

Given that HCF of 35 and 45 is 5cm

LCM of 35 and 45 is 63*a

Find

We need to find the value of a

Solution

Now ,

Given that HCF of 35 and 45 is 5cm

LCM of 35 and 45 is 63*a

As we know that

HCF × lcm = product of two numbers

∴ 5×63×a = 35×45

∴ a = $\frac{35*45}{5*63}$

∴ a = 5

Hence the value of a is 5
