The calculator finds all factors of each number 13 and 1202 by checking all corresponding divisors automatically from 1 to the given number, then it identifies the biggest from the common factors. In this way, the GCF is found. The calculateor uses two inputs to support the GCF and LCM calculation of fractions or ratios (as these are common math exercises). The Least Common Multiple And Greatest Common Factor Calculator will calculate:

- the LCM and GCF of two numbers

**Least Common Multiple And Greatest Common Factor Calculator Parameters:** Numerator and denominator are both integers; the calculator works only for two numbers at once.
