In Mathematics, B.M.M stands for the largest divisor against the common, the largest number that can divide two or more numbers without the remainder. B.M.M. Helps us simplify numbers or solve math problems associated with fractional numbers and proportions.

method of decomposition to the first factors to find B.M.M.:
- break down each number into first factors.
- find common factors between numbers.
- select and multiply the smallest common powers of the factors.
