28/63 = 4/9 28/7=4 63/7=9
The same as the GCF of 28 and 7 (7 is the remainder when you divde 63 by 28).
Expressed as a proper fraction in its simplest form, by dividing the numerator and denominator by 7, 28/63 is equal to 4/9 or four ninths.
prime factorizing, 63 = 3*3*7 and 28 = 2*2*7, so the answer is 7.
7/9 - 4/7 = 49/63 - 36/63 = 13/63
28/63 = 4/9 28/7=4 63/7=9
cause 4/7 = 36/63 and 28/63
63/28 - 4/28 = 59/28
3 + 4 = 27 + 28 = 55 7... 9 ... 63 .. 63 .. 63
4/7 & 4/9 Bring to the same denominator of 63 ( 7 x 9) Hence we multiply the numerators by 9 & 7. (4 x 9) / 63 & (4 x 7) / 63 36/63 & 28/63 Since they are the same denominator , we now. compare the numerators 36 > 28 It follows 36/63 > 28/63 => 4/7 > 4/9
The same as the GCF of 28 and 7 (7 is the remainder when you divde 63 by 28).
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 7 is a factor of 28 and 63 and 7 is a prime number.
The factors of 28 are: 1, 2, 4, 7, 14, 28 The factors of 63 are: 1, 3, 7, 9, 21, 63
The greatest common factor (GCF) of two numbers is the largest number that divides evenly into both numbers. To find the GCF of 28 and 63, we need to list the factors of each number. The factors of 28 are 1, 2, 4, 7, 14, and 28, while the factors of 63 are 1, 3, 7, 9, 21, and 63. The largest number that appears in both lists is 7, so the GCF of 28 and 63 is 7.
Factors of 28: 1, 2, 4, 7, 14, 28Factors of 63: 1, 3, 7, 9, 21, 63Factors of 49: 1, 7, 49GCF (28, 63, 49) = 7
