१४-२१ १३-१७ १०-३० ५०-५२ १५-१६ सहमुळ संख्या आहेत की नाही ते सांगा
Given : pair of numbers संख्यांची जोडी
14-21
13-17
10-30
50-52
15-16
To find : सहमुळ संख्या आहेत की नाही
Pairs are coprime or not
Solution:
co prime numbers सहमुळ संख्या
co prime numbers does not have any prime number as common factor
14-21
14 = 2 * 7
21 = 3 * 7
7 is common factor
Hence 14-21 not co prime
13-17
13 and 17 both are prime numbers
Distinct prime numbers are always coprime
13-17 are co prime सहमुळ संख्या
10-30
10 = 2 * 5
30 = 2 * 3 * 5
2 and 5 are common factors
Hence 10-30 not coprime
50-52
50 = 2 * 5 * 5
52 = 2 * 2 * 13
2 is common factor
Hence 50-52 not coprime
15-16
15 = 3 * 5
16 = 2 * 2 * 2 * 2
No Common Factor
Hence 15-16 are co prime सहमुळ संख्या
13-17 are co prime सहमुळ संख्या
15-16 are co prime सहमुळ संख्या
