Complete the chart by filling the cells with H.C.F. of the numbers. H.C.F. 15 16 18 32 24 9 1 8 2 4 4 28 40 8

Given, Table is, H.C.F. 15 16 18 32 24 9 1 8 2 4 4 28 40 8 We, need to complete the given table by filling in the highest common factors of the given numbers. We, know that, The Highest Common Factor (H.C.F.) of two numbers is the highest possible number which divides both the numbers exactly. Therefore, the H.C.F. of the given numbers are as follows, The first numbers are 9 , and 15 , such as, The highest factor divisible by these numbers is 3 . The, next numbers are, 9 and 16 , The highest factor divisible by these numbers is 1 . The H.C.F. of 9 and 18 is 9 . The H.C.F. of 9 and 32 is 1 . The H.C.F. of 9 and 24 is 3 . The H.C.F. of 8 and 15 is 1 . The H.C.F. of 8 and 16 is 8 . The H.C.F. of 8 and 18 is 2 . The H.C.F. of 8 and 32 is 8 . The H.C.F. of 8 and 24 is 8 . The H.C.F. of 4 and 15 is 1 . The H.C.F. of 4 and 16 is 4 . The H.C.F. of 4 and 18 is 1 . The H.C.F. of 4 and 32 is 4 . The H.C.F. of 4 and 24 is 4 . Hence, the completed table of H.C.F. numbers are as shown below, H.C.F. 15 16 18 32 24 9 3 1 9 1 3 8 1 8 2 8 8 4 1 4 1 4 4 28 1 4 2 4 4 40 2 8 2 8 8
