Web17 mrt. 2013 · Co prime numbers are those numbers that donot have any common factors. For example, 14 and 15. Individually none of them is prime number because 14=2 x 7 and 15 = 3 x 5. But they (14 and 15) donot have any common factors. So they’re called co-prime numbers (when they’re given together). WebThe Least Common Multiple (LCM) of two co-primes is always their product. For example, 5 and 9 are co-prime numbers. Hence, LCM (5, 9) = 45. 1 forms a co-prime number …
