The factors of 57 are:1, 3, 19, 57The factors of 84 are:1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 84The common factors are:1, 3
The term common factors specifically refers to the factors shared by two or more numbers. Since 84 is a single number, you could say that it shares all of its factors with itself.The factors of 84 are: 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, and 84.You need at least two numbers to find something in common between them. If that's 8 and 4, the common factors are 1, 2 and 4.
