"The" co-prime number is wrong; for any number, there are infinitely other numbers that are co-prime with it, not just one. Get the prime factors for 72. Then, any number made up of factors that DON'T include those prime factors is co-prime with 72. For example, 49 (which is 7 x 7), or 35 (5 x 7) are coprime with 72, since neither 5 nor 7 are among the prime factors of 72.
The factors of 18 are 1, 2, 3, 6, 9, and 18.The factors of 35 are 1, 5, 7, and 35.The only common factor is 1, so the greatest common factor is 1. This means they are relatively prime.The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together.The prime factors of 18 are 2, 3, and 3.The prime factors of 35 are 5 and 7.There are no common prime factors, therefore they are relatively prime, which means the greatest common factor is 1.18 = 2 x 3 x 3, 35 = 5 x 7. There is no common factor other than 11 - they are relatively primeThe GCF is 1.The GCF is 1.The GCF is 1.
Relatively prime or co-prime.
no first of all 16 is not a prime no so it can not fit for any prime no to be co prime
2 is the smallest prime number. It is co-prime with every odd number.
