Any two coprime numbers
The GCF of all the composite numbers under 100 is 1. For e.g 4 & 9 are composite numbers & their GCF is 1, so if we take other composite numbers along with 4 & 9 the GCF will be 1.
4 and 9 have a GCF of 1
Any two composite numbers who do not share the same prime factors.15 = 5x322 = 11x2So 15 and 22 have a GCF of 1
3 and 7?
Any pair of prime numbers as for example 19 and 23
5 and 7
Two composite numbers are considered relatively prime if their greatest common factor (GCF) is 1. For example, the pair of composite numbers 15 and 28 have a GCF of 1 because the factors of 15 are 1, 3, 5, and 15, while the factors of 28 are 1, 2, 4, 7, 14, and 28, and they do not share any common factors other than 1. Another example is the pair of composite numbers 21 and 34, as their factors are 1, 3, 7, 21 and 1, 2, 17, 34 respectively, and their GCF is also 1.
The pair of numbers whose GCF is 1 and LCM is 36 is 9 and 4. The numbers should be greater than their GCF and less than their LCM.
4 and 9 hope it helps!! : )
25 and 36
numbers which are co prime have a GCF as 1 For example *2,3 *37,47 *23,24
25, 49 and 121
