Question
Using Euclid's algortihm, find the HCF of:
504 and 1188

Answer

On dividing 1188 by 504, we get
Quotient = 2, Remainder = 180
$\therefore$ 1188 = 504 × 2+ 180
Dividing 504 by 180
Quotient = 2, remainder = 144
$\therefore$ 504 = 180 × 2 + 144
Dividing 180 by 144, we get
Quotient = 1, Remainder = 36
Dividing 144 by 36
Quotient = 4, Remainder = 0
$\therefore$ H.C.F. of 1188 and 504 is 36
