They all have a multiple of 504
28/36 Divide by the GCD (greatest common denominator) 28/4=7 36/4=9 Final answer=7/9
The lowest common denominator is 1/4 x 1/9 = 1/36. 1/4 = 36/4x1 x 1/36 = 9/36 7/9 = 36/9x7 x 1/36 = 28/36 28/36 - 9/36 = 21/36 = 7/12
63 ... 3, 7, 9, 21, 63 36 ... 2, 3, 4, 6, 9, 12, 18, 36 common factors ... 3, 9
To give a number in its simplest form, you need to identify any common divisors between the denominator and numerator. In this case, both 36 and 28 divide by 4. If we do this, we get 9/7. 9 and 7 have no common factors, and so 36/28 in its simplest form is 9/7.
28 = 36 x 7/9 = 36/9 x 7 = 4 x 7
Factors of 7: 1, 7Factors of 36: 1, 2, 3, 4, 6, 9, 12, 18, 36GCF (7, 36) = 1
GCF of 36 63 and 72 is 9.
The common factors of 9 and 36 are 1, 3, and 9.
36
The LCD is 36
The common factors of 9 and 36 are: 1, 3, and 9
The Least Common Multiple (LCM) for 12 2 9 is 36.
