Just 1.
Factor out each term to get: 20 = 2² x 5 99 = 3 x 33 = 3² x 11 Since these terms don't have the common factor, the common factor is 1.
The only common factor is 1.
The least common factor of any set of integers is 1.
It is: 1
The greatest common factor of 21 and 54 is 3. The greatest common factor is the highest number that divides exactly into two or more numbers. factors of 21: 1, 3, 7, 21 factors of 54: 1, 2, 3, 6, 9, 18, 27, 54 The greatest common factor of 21 and 54 is 3.
No, they have the common factor 3.No, they have the common factor 3.No, they have the common factor 3.No, they have the common factor 3.
The greatest common factor of 20 and 555 is 5. The prime factorization of 20 is 2*2*5 The prime factorization of 555 is 3*5*37 So the greatest common factor is 5.
3 and 20 have no common factor so LCM is 3 x 20 ie 60
1 is the answer
The GCF is 1.
The GCF is 1.
The highest common factor is: 20
