Question

Q1. If the HCF of 20 and 35 is 5, LCM of 20 and 35 is 70a, then find the value of a​

Answer 1

Step-by-step explanation:

we know that

HCF(a,b)×LCM(a,b)=a×b

$5 \times 70a = 20 \times 35 \\ 70a = \frac{20 \times 35}{5} \\ 70a = 4 \times 35 \\ a = \frac{140}{7} \\ a = 20$

hope it helps u.

Answer 2

Step-by-step explanation:

VALUE OF a IS 2

SO 70×2 = 140 LCM
