7 is a factor of 28 because 4 x 7 equals 28. 7 is a factor of 63 because 9 x 7 = 63. That makes 7 a common factor of 28 and 63. The factors of 28 that are larger than 7 are 14 and 28. The factors of 63 that are larger than 7 are 9, 21 and 63. Since none of those numbers are the same, that makes 7 the greatest common factor of 28 and 63.
Because 63 is the smallest number that both 7 and 9 will divide into evenly with no remainder.
The same as the greatest common factor of 35 and 28 (where 28 is the remainder of the division of 63 by 35).
The Greatest Common Factor (GCF) of 7 and 63 is 7.Since 7 is a factor of 63, it is automatically the GCF.
