They are 1 and 7
Greatest common factor= 7 The greatest common factor is the factor that all these numbers have in common. It helps to make a list of all the number's factors. 28- 2, 2, 7 35- 5, 7 42- 2, 3, 7 All of these numbers have 7 as a factor, therfore 7 is the greatest common factor
7 is the gcf of 28 35 and 42
The least common multiple of the numbers 28, 35 and 42 is 420.
Common factors of 42 and 28 are: 1, 2, 7, and 14.
The common factors are: 1, 7
Factors are numbers you can multiply together to get another number. Common factors are the factors two or more numbers have in common. 28: 1, 2, 4, 7, 14, 28 42: 1, 2, 3, 6, 7, 14, 21, 42 The common factors of 28 and 42 are 1, 2, 7 and 14.
1, 2, 7, and 14 are common divisors (and common factors) of 28 and 42.
1 and 7, the GCF.
