Answer 1

$\huge{\underline{\mathtt{\red{A}\pink{N}\green{S}\blue{W}\purple{E}\orange{R}}}}$

By Euclid's division algorithm, we have

dividend = ( divisor × quotient) + remainder

=(53×34)+21

=(1802+21)=1823

Hence, the required number is 1823.

Answer 2

dividend = ( divisor × quotient) + remainder

=(53×34)+21

=(1802+21)=1823

Hence, the required number is 1823.
