Binomial Coefficient Crossed GCD Concern (Posted on 2023-07-08) Difficulty: 3 of 5
Is nCm*gcd(m,n)/n always an integer, whenever each of n and m is a positive integer with n≥m?

If so, prove it.
If not, provide an example.

Note: nCk=n!/{(k!)*(n-k)!} is called Binomial coefficient. It is also read as "n choose k".
