Question

lf 5 and 7 is deducted from 257 and 457, respectively, then what will be the HCF?​

Answer 1

Answer:

18.000000000000000000000000

Answer 2

Given,

The main numbers are = 257 and 457

5 and 7 are respectively deducted from the main numbers.

To find,

HCF of the numbers after the deduction.

Solution,

We can simply solve this mathematical problem by using the following mathematical process.

First number after deduction = 257-5 = 252

Second number after deduction = 457-7 = 450

HCF of the deducted numbers,

Prime factorization :

252 = 3×3×2×2×7

450 = 3×3×2×5×5

Common factors = 3,3,2

HCF = 3×3×2 = 18

Hence, the value of HCF is 18
