Question

Find the largest number which gives out reminders 2 and 5 when used to divide 80 and 122.

Answer 1

78 and 117 are used to divide 80 and 122 for get reminder 2 and 5

Answer 2

Answer:39

Step-by-step explanation:

Since when 80 is divided by the number remainder is 2. Hence 80 – 2 = 78 will be divisible by the number.

Similarly, when 122 is divided by the number remainder is 5. Hence 122 – 5 = 117 will be divisible by the number

Finding out the HCF of 78 and 117

⇒HCF(78 , 117) = 39
