1.	Which of the following are pairs of co-primes 8, 14
Answer» ANSWER: FACTORS of 14=1,2,7 Factors of 35=1,5,7 ⇒ COMMON FACTOR =1,7 ∴ (14,35) is not PAIR of co-prime. Factors of 18=1,2,3,6,9 Factors of 25=1,5 ⇒ Common factor =1 ∴ (18,25) is pair of co-prime. Factors of 31=1,31 Factors of 93=1,3,31 ⇒ Common factor =1,31 ∴ (31,93) is not pair of co-prime. Factors of 32=1,2,4,8,16 Factors of 62=1,2,31 ⇒ Common factor =1,2 ∴ (32,62) is not pair of co-prime.

ANSWER:

FACTORS of 14=1,2,7

Factors of 35=1,5,7

⇒ COMMON FACTOR =1,7

∴ (14,35) is not PAIR of co-prime.

Factors of 18=1,2,3,6,9

Factors of 25=1,5

⇒ Common factor =1

∴ (18,25) is pair of co-prime.

Factors of 31=1,31

Factors of 93=1,3,31

⇒ Common factor =1,31

∴ (31,93) is not pair of co-prime.

Factors of 32=1,2,4,8,16

Factors of 62=1,2,31

⇒ Common factor =1,2

∴ (32,62) is not pair of co-prime.
