Yes because you divide by 2 and that is 15 over 98
27/196 this is the lowest term
2/3
The fraction 79/196 cannot be reduced any more.
188
196, 30, 58.
30/75 is reduced to 2/5.
The reduced fraction for 21/30 is 7/10
30 over 42 can be reduced to 5/7
30 is an integer and not a fraction. An integer cannot be reduced.
The GCF is 2.
As a product of its prime factors: 2*2*7*7 = 196
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...
