							Dear Student

Given,
Number of army contingent members=616
Number of army band members = 32

If the two groups have to march in the same column, we have to find out the highest common factor between the two groups.
HCF(616, 32), gives the maximum number of columns in which they can march.

By Using Euclid’s algorithm to find their HCF, we get,
Since, 616>32, therefore,
616 = 32× 19 + 8

Since, 8 ≠ 0, therefore, taking 32 as new divisor, we have,
32 = 8 × 4 + 0
Now we have got remainder as 0, therefore, HCF (616, 32) = 8.
Hence, the maximum number of columns in which they can march is 8.
