If you really want the "least" common factor, then you'll only get one of them. If
there were two of them, then you'd want to know which least common factor was
less than the other least common factor.
The least common factor of 105 and 84 is ' 1 '. In fact, the least common factor of
any two numbers is ' 1 '. So if you want to look at it that way, you'd have to say
that it's also the most common factor. (But not the greatest one.)
The factor pairs of 84 are (84,1), (42,2), (28,3), (21,4), (14,6), and (12,7). The factor pairs of 105 are (105,1), (35,3), (21,5), and (15,7)
1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 84
1, 3, 5, 7, 15, 21, 35, 105
It is 1 but the highest common factor is 21
84 = 1 x 84
84 = 2 x 42
84 = 3 x 28
84 = 4 x 21
84 = 6 x 14
84 = 7 x 12
84 is one of 16 factors of 168.
Since 12 is a factor of 84, all of its factors are common.
The factors of 19 are: 1, 19 The factors of 79 are: 1, 79
60, 72, 84, 90 and 96 each have twelve factors.
The common factors are: 1, 7
1, 3, 7 and 21
The GCF is 21.
The GCF is 21.
By prime factoring 84 you get 2x2x7x3. These are all the factors of 84
The prime factors of 60 are 2, 2, 3, and 5.The prime factors of 105 are 3, 5, and 7.The prime numbers that are factors of both 60 and 105 are 3 and 5.
1,2,4,7,8,14,28,and 56 are the factors of 56 1,2,3,4,6,7,12,14,21,28,42,and 84 are the factors of 84. wait did you mean 56 and 84 or the number 5684?
The GCF is 5.
