Ex 3.4, 5 Which of the following numbers are co-prime? (a) 18 and 35 If two Numbers have common factor 1, They are Co-prime Numbers Factors of 18 1 × 18 = 18 2 × 9 = 18 3 × 6 = 18 6 × 3 = 18 We stop here as 3 & 6 have occurred earlier So factors of 18 are 1, 2, 3, 6, 9, and 18 Factors of 35 1 × 35 = 35 5 × 7 = 35 7 × 5 = 35 We stop here as 7 and 5 have occurred earlier So factors of 35 are 1, 5, 7, 35 Since common factor is 1, They are co-prime numbers
