No.
No, it is 2
No, 42 is a multiple of 3. 3 is a factor of 42.
The greatest common factor of 28 and 42 is 7
the only factor (divisor) between 30 and 64 are 2, this is also a factor of 42 & 196 working upwards: 1 is always a factor of integers 2 is a factor of all even numbers 3 is a factor of 30 & 42, but not 64 or 196 4 is a factor of 64 & 196, but not 30 or 42 5 is a factor of 30, but not the others 6 is a factor of 30 & 42, but not 64 or 196 7 is a factor of 42, but not the others 8 is a factor of 64, but not the others 9 is not a factor of any of the numbers 10 is a factor of 30, but not the others I could continue, but it gets worse from there, with only occasional numbers being factors...
The GCF is 1.
No, 4 is not a factor of 42.
The GCF of 4, 30 and 42 is 2.
2 is the answer.
No, it is 2
The GCF is 2.
No, because 4 does not fit into 18 evenly.
28 is not a factor of 42.
6 is a factor of 42.
common factor is 42. so it's 35/42 + 24/42 = 59/42 = 1&17/42
No, 42 is a multiple of 3. 3 is a factor of 42.
8 is not an integer factor of 42.
It can be. 42 is a proper factor of 84.
