Definition of eo-primes or relatively primes: Two numbers are said to be co-prime or relatively prime If their HCF IS 1 Hence to prove 847 and 2160 as co-prime numbers we will find their HCF and which should be 1
New steps to find HCF will be as under
2160 = 847 x 2+ 466 847 = 466 ×1 +381 466 = 381 x 1 + 85 381 =85 x 4+ 41 85 =41 x 2+3 41 =3 x 13+ 2 3 =2 x 1+1 2 =1 x 2+0
Therefore, the HCF=1 Hence, the numbers are co-primes (relatively prime).
