Factors of 28: 1, 2, 4, 7, 14, and 28 .
To find the prime factors of 28 start with any factor pair of 28 and keep factoring the composite factors until all the factors are prime. 28 2 x 14 2 x 2 x 7 The three prime factors of 28 are 2, 2, 7.
To find the LCM of 28 and 5 you start by splitting these into their prime factors: 28 = 2x2x7 5 = 5 The next step would be to identify any common factors. In this case, there are none, and so we take all the factors, and multiply them together to find the LCM: 2x2x7x5 = 140 Thus the LCM of 28 and 5 is 140.

Answer:The common factors of 16 and 28 are 1, 2, and 4.Definition: A factor is a divisor - a number that will evenly divide into another number. The common factors of two or more numbers are all the factors that the numbers have in common.Methods:One way to determine the common factors is to find all the factors of the numbers and compare them.The factors of 16 are 1, 2, 4, 8, and 16.The factors of 28 are 1, 2, 4, 7, 14, and 28.The common factors are 1, 2, and 4.
28, 56, 84, and all other multiples of 28 that are factors of other numbers are also divisible by 28.
