Question

what is the largest number that divides 70 and 125 , leaving remainder 5 and 8 respectively
​

Answer 1

Answer:

as 5 and 8 are the remainder so we calculate the HCF of( 70-5) and (125-8)

70-5=65=13×5

125-8=117=13×3×3

so the largest number is 13

Answer 2

Answer:

for this    177=65×1+52 {∵dividend=divisor×quotient+remainder}

→              65=52×1+13

→              52=13×4+0

               HCF=13
