Question

find the HCF of 21 and 27

Answer 1

Greatest common factor (GCF) of 21 and 27 is 3. We will now calculate the prime factors of 21 and 27, than find the greatest common factor (greatest common divisor (gcd)) of the numbers by matching the biggest common factor of 21 and 27.

Answer 2

HOLA

==============

By Euclid's division algorithm we have

27 > 21

27 = 21 × 1 + 6

21 = 6 × 3 + 3

6 = 3 × 2 + 0

HCF ( 27 , 21 ) = 3
