Factors of 28... 1,2,4,7,14,28 Factors of 44... 1,2,4,11,22,44 Common factors therefore are 1,2 & 4
The common factors of 44 and 55 are: 1 and 11
Common factors of 44 and 60 are: 1, 2, and 4.
Common factors of 22 and 44 are: 1, 2, 11, and 22.
The GCF of 21, 33, and 44 is 1. Note that the factors of 21 are 1,3,7 and 21 itself. Of these none is a factor of 33 and 44 except 1. You can look at the prime factorization of the numbers. Note there is no prime in common with all three numbers in the set, so the GCF is 1. 3x7=21 11x3=33 11x22 =44
The GCF is 1.
The first question you need to investigate: Is there ANYnumber that is a common factor of 21, 30, and 44 ?If we can't find at least two of them, then we don't have to worry about "greatest".The factors of 21 are: 1, 3, 7, and 21.The factors of 30 are: 1, 2, 3, 5, 6, 10, 15, and 30.The factors of 44 are: 1, 2, 4, 11, 22, and 44.The only factor common to 21, 30, and 44 is '1'.Technically, I guess the answer to the question is 'Yes'. There is one common factor, so it'salso the greatest.
The common factors of 18 and 44 are 1 and 2.
The common factors of 44 and 70 are: 1 and 2
The Common Factors of 42 and 44 are 1, 2
The common factors of 44 and 121 are: 1 and 11
Common factors of 26 and 44 are: 1 and 2.
The common factors of 32 and 44 are: 1, 2, and 4
44 and 65 share no common factors aside from 1.
The common factors of 42 and 44 are 1 and 2.
The common factors of 44 and 132 are 1, 2, 4, 11, 22 and 44.
