Answer 1

Answer:

15 is the smallest number

Step-by-step explanation:

first substrate 5 from the number and then find H.C.F

Answer 2

Answer:

15

Step-by-step explanation:

• 140 is divided by the number a remainder5 is left,
• thus,140-5=135 is divided by that number
• similarly, when we divide 170 by that number a remainder 5 is left
• thus,170-5=165is divided by that number
• 155 is divided by that number a remainder 5 is left
• thus,155-5=150 is divided by that number
• Hence,the required number is the hcf of135 ,165,150
• then we find the answer by division method in hcf.
