If you really want the 'highest', then you only get one. If there were two
highest ones, then you'd want to know which highest one is higher than
the other highest one. Then, whichever one it was would really be the
highest one, and the other one wouldn't be.
The highest common factor of 12 and 84 is 12.
The GCF is 12.
It is 12. Beacause the factors of 36 are: 1,36,3,12,4,9,6 and the factors of 84 are: 1,84,7,12 12 is the highest factor that both numbers have in common.
Since 12 is a factor of 84, all of its factors are common.
The factors of 84 are 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 84. For them to be common, they need to be compared to another set of factors.
132 factors into 4 X 3 X 11 and 84 factors into 4 X 3 X 7. Therefore, their highest common factor is 4 X 3 = 12.
It is 14
The factors of 12 are: 1,2,3,4,6,12 The factors of 44 are: 1,2,4,11,22,44 Thus the greatest common factor of 12 and 44 is 4
The common factors are: 1, 2, 3, 4, 6, 12. 12 is the greatest common factor of 72 and 84. All the factors of 12 will therefore divide by both 72 and 84.
The GCF of 12 and 84 is 12Method:One way to determine the common factors and greatest common factor is to find all the factors of the numbers and compare them.The factors of 12 are 1, 2, 3, 4, 6, and 12.The factors of 84 are 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, and 84.The common factors are 1, 2, 3, 4, 6, and 12. Therefore, the greatest common factor is 12.Since 12 is a factor of 84, it is automatically the GCF.
It is 7
The highest common factor of 28, 49 and 84 is 7.
