Question

Find the HCF and LCM 17, 102, 170

Answer 1

LCM = 510

HCF = 17

Step-by-step explanation:

We have to find the LCM and HCF of 17, 102, 170

First of all we find the factors of the given numbers.

17 = 1×17

102= 2×3×17

170 = 2×5×17

Now, LCM is the product of common terms in all the three factors and the rest terms. And HCF is the common term in all factors.

17 is common in all the three factors. Hence, HCF = 17

And LCM = 17×2×3×5×1 = 510
