HCF (616,32) is the maximum number of columns in which they can march.
Step 1: First find which integer is larger.
Step 2: Then apply the Euclid's division algorithm to 616 and 32 to obtain
Repeat the above step until you will get remainder as zero.
Step 3: Now consider the divisor 32 and the remainder 8, and apply the division lemma to get
Since the remainder is zero, we cannot proceed further.
Step 4: Hence the divisor at the last process is 8
So, the H.C.F. of 616 and 32 is 8.
Therefore, 8 is the maximum number of columns in which they can march.
