The greatest common factor of two numbers has to show up on the lists of factors of both numbers.
A factor tree will show you the prime factorization of 88. Comparing that prime factorization of 88 and another number will you show you the GCF between the two. You need at least two numbers to find a GCF.
The factors of 184 are: 1, 2, 4, 8, 23, 46, 92, 184 The factors of 207 are: 1, 3, 9, 23, 69, 207 The common factors are: 1, 23 The Greatest Common Factor: GCF = 23
The greatest common factor (GCF) of 25 and 105 is 5. To find the GCF, you need to determine the largest number that divides evenly into both 25 and 105. In this case, 5 is the largest number that is a factor of both 25 (5 x 5) and 105 (5 x 21). Therefore, the GCF of 25 and 105 is 5.
Oh honey, the greatest common factor of 18, 42, and 60 is 6. It's like finding the perfect little black dress that fits all three of them, just divide each number by 6 and you'll see what I mean. Math can be a real fashion show sometimes, darling.
