# What is the second integers, if first is 77?

The HCF and LCM of two positive integers are 35 and 385 respectively. If one of the integers is 77, what is the other integers?

- 350
- 210
- 175
- None of the above

**Answer: (3) 175
Explanation:-
**The LCM & HCF of two numbers are = 385 & 35

One number = 77

Let be the other is 175.

Formula-

HCF x LCM = one number x second number

35 x 385 = 77 x X

X = 35 x 385/77

X = 175

Hence, the other number is 175
