<span>To get the Greates Common Factor (GCF) of 21 and 40 we need to factor each value first and then we choose all the copies of factors and multiply them:

Sensitivity analysis is the study of how the uncertainty in the output of a mathematical model or system (numerical or otherwise) can be divided and allocated to different sources of uncertainty in its inputs.
