3, 12, 30
5 + 2 = 7
Since C can be any number, the answer can be any factor of 60.
56
The greatest common factor of 60 and 70 is 10
2, 4, 6, 10, 12, 20, 30, 60 add up to 144.
the sum of my digits is 6? answer=60
A number is divisible by 3 if the sum of its digits is divisible by 3. The sum of the digits of 60 is 6 + 0 = 6, which is divisible by 3, so, yes, 60 is divisible by 3. 60 ÷ 3 = 20
So... the number has to be between 55 & 60 - and the sum of its digits must total 13... The only number that satisfies both rules is 58 !
