Prime factorisation by hand didn't take long and it revealed 11 factors. Each can be present or absent for each factor so 211 = 2048 in total.

200,560,490,130 is the product of the first 11 prime numbers. To find the total number of factors of a number, determine the numbers prime factors, then add 1 to each exponent and then multiply those numbers together:
2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 = 2,048
