If two number which have least common factor 3 and 2 respectively are added Find the least common Prime factor of the new number formed
The two numbers will be of the form 3x and 2y. x is an odd number.(because 3 is the least factor) Therefore 3x is an odd number and 2y is an even number. Therefore, 3x + 2y is an odd number.
Two natural numbers which have common prime factors are called Co- Primes.
If two numbers are co-prime, they have exactly two common factors
