1
The greatest common factor of 3 and 7 is 1.
There is only one common factor of 5, 3, 7: 1
The least common factor of any set of numbers is 1.
The only common factor is 1. There is no proper common factor.
The lowest common factor is: 1
The greatest common factor of 7 and 243 is 1. Prime factorizations: 7 = 7 243 = 3 x 3 x 3 x 3 common factors - no primes, so only common factor is 1: 7 x 1 = 7 243 x 1 = 243
No, they have the common factor 7.No, they have the common factor 7.No, they have the common factor 7.No, they have the common factor 7.
The least common factor of any set of integers is 1.
6 factors into [2 3] 21 factors into [3 7] Common factor is [3]◄
Factor out each term to get: 77 = 7 x 11 105 = 5 x 21 = 5 x 3 x 7 = 3 x 5 x 7 Since these terms have 7 in common, 7 is the common factor.
33 isn't, but 3 is: 21 = 3 x 7 24 = 3 x 8 The only common (and hence greatest common) factor is 3 as there is no common factor (other than 1) between 7 and 8.
3 and 7 do not have a common factor, so their LCM is 3 x 7 = 21The LCM is: 21
