The correct answer is: c) 46 and 87
Further explanation:
Let us define relatively prime numbers first:
"Relatively prime numbers are those numbers whose greatest common factor is 1"
So,
a) 20 and 76
[tex]20: 1,2,4,5,10,20\\76: 1,2,4,76[/tex]
The GCF is 4 so the pair is not relatively prime.
b) 25 and 65
[tex]25: 1,5,25\\65: 1,5,13,65[/tex]
The GCf is 5 so the pair is not relatively prime.
c) 46 and 87
[tex]46: 1,2,23,46\\87: 1,3,29,87[/tex]
GCF is 1 so the pair is relatively prime.
d) 63 and 117
[tex]63:1,3,7,9,21,63\\117:1,3,9,13,39, 117[/tex]
GCF is 9 so the pair is not relatively prime.
Hence, option C is correct
