LCM and HCF of two numbers are 140 and 5 respectively. If one of the numbers is 35, then find the other number.
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 20.
LCM = 140
HCF = 5
One number = 35
Number1 × Number2 = LCM × HCF
Let other number = x
35 × x = 140 × 5
35x = 700
x = 700 ÷ 35 = 20
