Question

If the HCF of 35 and 45 is 5. LCM of 35 and 45 is 63xa. Find the value of a

Answer 1

Step-by-step explanation:

Step-by-step explanation:

/* We know that ,

If m, n are two positive numbers then

HCF(m,n) × LCM(m,n) = m × n */

Here,

m = 35 , n = 45,

HCF(35,45) = 5,

LCM(35,45) = 63 × a ,

Therefore,

Value of a = 5

Answer 2

Answer:

a = 5

Step-by-step explanation:

HCF (35, 45) = 5

LCM (35, 45) = 63a

We know that HCF x LCM = Product of the two numbers

∴ 5 x 63a = 35 x 45

a = (35 x 45)/(5 x 63) = 5

∴a = 5
