Primer numbers can only be divided by one and itself.
The equation is given as:
[tex]\mathbf{abc = 105}[/tex]
Assume a = 5.
So, we have:
[tex]\mathbf{5bc = 105}[/tex]
Divide through by 5
[tex]\mathbf{bc = 21}[/tex]
Assume b = 7
[tex]\mathbf{7c = 21}[/tex]
Divide through by 7
[tex]\mathbf{c = 3}[/tex]
So, we have:
[tex]\mathbf{a = 5, b = 7, c = 3}[/tex]
The sum is represented as:
[tex]\mathbf{a + b + c =5 + 7 + 3}[/tex]
[tex]\mathbf{a + b + c =15 }[/tex]
Hence, the sum of a, b and c is 15.
