How many factors are there for X = 2^7 * 5^4 * 7^8 which are neither the factors of Y = 2^3 * 5^2 * 7^5 nor of Z = 2^5 * 5^3 * 7^3

Hi78 = 2*3*13So x = 2^8*3*5^4*13If the powers of 2 are 6 or 7 or 8, then the factors won't be common between the first number and the other two numbers. Such cases would be 3*2*5*2 = 60Similarly if the power of 5 is 4, there will not be common factors. However we need to keep in mind that we have already counted the cases when 2 is 6,7,8 and 5 is 4. So we should not count these cases.Hence required factors would be 5*2*1*2 = 20Similarly, for 3, we will have 5*4*2 = 40The cases where 13 is present have already been counted so we should not count them again. Thus, the required number of cases would be 60 + 20 + 40 = 120Hope that helps.

Hi Abhishek, To find the remainder when a number is divided by 25, we have to find the remainder when the last two digits of the number is divided by 25.The remainder when 69 is divided by 25 is 19.1643276550 is divisible by 25 and 19 is the remainder.Hence, the required answer is 19.Hope that helps.Thanks,Varun.
