Find the sum of divisor of 360 (by the formula which is taken as photo)
Answers
Answer:
first factorise 360 into its prime factors product then you get 360=2^3x3^2x5^1 this is another formula but you will get answer substitute 3,2,1 in N1,n2,n3 and 2,3,5 in P1,P2,p3 so you get the answer I hope it helps you please mark me as brainliest by A L V Sahasra
Answer:
If the prime factorization of n is
n=∏kpakk,
where the pk are the distinct prime factors and the ak are the positive integer exponents, the sum of all the positive integer factors is
∏k(∑i=0akpik).
For example, the sum of all of the factors of 120=23⋅3⋅5 is
(1+2+22+23)(1+3)(1+5)=15⋅4⋅6=360.
For proper factors, subtract n from this sum. This may or may not be faster, depending on the number and how you'd get the prime factorization, but this is the typical technique for high school contest problems of this sort.
