NettetThe whole idea is to start with the GCD and recursively work our way backwards. This can be done by treating the numbers as variables until we end up with an expression that is a linear combination of our initial numbers. We shall do this with the example we used above. We start with our GCD. We rewrite it in terms of the previous two terms: NettetThat is, the GCD of two numbers can be expressed as an integral linear combination of the two numbers. Remark-1. An interesting corollary follows from this result. An integer c can be written as an integral linear combination of two integers a and b if and only if c is a multiple of \(d = \left( {a,b} \right
