5,7 3,5 are co-primes
False. Co-primes are not the same as twin primes.Co-primes are any numbers having no common factorsother than 1. Examples of co-primes are 8 and 9 or 15 and 32.Twin primes are pairs of prime numbers exactly 2 apart such as 11 and 13 or 659 and 661.
The numbers, 2 and 5, are co-primes because they both have just two factors, 1 and themselves.
215 and 216 are co-prime.
Two distinct prime factors, four altogether.
Numbers are co-prime, or relatively prime, when their GCF is 1.
Any number greater than one can be co-prime. I guess the answer is 49.
Multiply them together.
There are for pairs of co-primes between 1 and 25. They are (3, 5), (5, 7), (11, 13), and(17, 19).
Find their GCF. If the GCF of two numbers is 1, the numbers are co-prime.
No. 1 is not their only common factor.
