The highest common factor is the greatest number which both numbers can divide by evenly. In this case, the greatest number 40 can divide by is 40. 80 can also divide by 40, and so this is a common factor. As no numbers greater than 40 will be able to divide 40 evenly, the hcf of 40 and 80 is 40.
The HCF of 4 and 90 is 2.
The HCF of 40 & 12 is... 4
The hcf of 45 and 40 is 5.
HCF(40, 63) = 1

The Greatest Common Factor of 80, 85, 90: 5
The highest common factor is the greatest number which both numbers can divide by evenly. In this case, the greatest number 40 can divide by is 40. 80 can also divide by 40, and so this is a common factor. As no numbers greater than 40 will be able to divide 40 evenly, the hcf of 40 and 80 is 40.
The HCF of 4 and 90 is 2.
2 x 2 x 2 x 5 ---- 40
85
The GCF is 10.
Write the data in an increasing order:40 60 79 80 90 90 98 99Since the number of data is even, the median will be the average of the two data that are in the middle (80 and 90).So the median of the data is 85, (80 + 90)/2.
The HCF of 40 & 12 is... 4
The hcf of 45 and 40 is 5.
HCF(40, 63) = 1
The GCF is 30.
