2014 = 2 x 19 x 53

2013 = 3 x 11 x 61

------------------------------ x

2014*2013 = 2 1 2^1 x 3 1 3^1 x 1 1 1 11^1 x 1 9 1 19^1 x 5 3 1 53^1 x 6 1 1 61^1

The number of the factors is (1+1)(1+1)(1+1)(1+1)(1+1)(1+1) = 64 \boxed{64}

These numbers may also be called 'divisors'.

Prime factorization of 2014 is 2 19 53 2\cdot 19\cdot 53

Prime factorization of 2013 is 3 11 61 3\cdot 11\cdot 61

Adding 1 1 to each exponent and multiply the resulting exponent yields 64 \boxed{64}

Factors and divisors are same?
