Co prime Numbers From 1 to 100: What Are Co-prime Numbers

img-icon

Co Prime Numbers From 1 to 100: When two numbers have 1 as the common factor, they are called Co-Prime Numbers. Two prime numbers will always be a co-prime number since the prime number is divisible by 1 and the number itself. Students looking for Co Prime numbers from 1 to 100 must know that relatively prime and mutually prime numbers are examples of co-prime numbers. 

Prime numbers and co-primes are also used in engineering to avoid resonance and ensure equal wear of cogwheels (by ensuring that all cogs fit in all depressions of the other wheel). So students wanting to pursue engineering or physics in future must have a perfect understanding of these concepts. In this article, students will find full details for Co Prime Numbers 1 to 100, Co-Prime number 1 to 50, Co Prime number definition and more.

Tips to Find Co Prime Numbers From 1 to 100

Some of the easiest ways to find Co-Prime numbers are to look at some Co-Prime number examples as given below:

  • Any number which is compared with number 1 will become a co-prime number. Because 1 is Co prime with every number.
  • Any sum of two numbers will become co-prime with the product of the two numbers. Example: {2+3 = 5} and {2 x 3 = 6}. Sum of 2,3 = 5 and Product of 2,3 = 6. So {5,6} are co-prime numbers.
  • Any two prime are co-prime numbers. Thus, if you are aware of prime numbers, you can easily write infinite sets of co-prime numbers.
  • Two successive numbers or integers are always co-prime numbers. So, you can easily write 2 successive integers when you are asked to write a co-prime number.
  • 2 even numbers cannot form a co-prime number. So, when you are asked to find the co-prime numbers and if you find 2 even numbers, then mark them as Non-Co-Prime numbers.
Q.1: What are 5 pairs of co-prime numbers from 80 to 100?

Ans: The 5 pairs of co-prime numbers from 80 to 100 are {80,81}, {87,88}, {91,92}, {97,98} and {99,100}.

Q.2: What are the two pairs of co-prime numbers between 41 to 60?

Ans: The 2 pairs of co-prime numbers between 41 to 60 are {46,47} and {59,60}.

Q.3: What are co-prime numbers up to 100?

Ans: There are many co prime numbers from 1 to 100. The 575 sets of co prime numbers from 1 to 100 are provided on this page.

Q.4: Are 1 and 1 co-prime?

Ans: Any two numbers whose GCD is (1,1) is a co-prime number. Since the GCD of 1 and 1 is (1,1), it is a co-prime number.

Q.5: Is 11 and 12 co-prime?

Ans: Yes, two successive integers are always co-prime numbers. Thus, 11 and 12 are co-prime numbers.
