Expressing each number as the product of prime number helps a lot in finding gcf.Prime factorization of 48x5 = 2x2x2x2x3x5Prime factorization of 36x3 = 2x2x3x3x3It is clear that 2x2x3 is the greatest common factor.So, gcf is 12.
I assume you mean:2x^5-48x^5-50xSo, 2x can be divided out, leaving:2x (x^4-24x^4-25)
It's a sequence of 2x2=4, 4x3=12,12x4=48,so then 48x5=240. The answer is 240 hamsters.
