no of factors of 1800?
Read Solution (Total 6)
-
- N = 1800 => 2^3 * 3^2 * 5^2 [a^x * b^y * c^z ..]
Total no. of factors of N can be calculated by (x+1)*(y+1)*(z+1)
=> (3+1) * (2+1) * (2+1)
=> 36
Ans : 36 - 10 years agoHelpfull: Yes(35) No(1)
- 1800= 3^2*2^3*5^2
no of factors = (2+1)*(3+1)*(2+1)= 36 - 10 years agoHelpfull: Yes(4) No(0)
- factors for 1800 is 2^3,3^2 and 5^2 so that for no of factor (3+1)*(2+1)*(2+1)=36
- 10 years agoHelpfull: Yes(1) No(0)
- x=1800
first 2^3*3^2*5^2
formula a^x*b^y*c^z......
then (x+1)*(y+1)*(z+1)=(3+1)*(2+1)*(2+1)
4*3*3=36
ans 36 factors - 10 years agoHelpfull: Yes(1) No(0)
- 1800=2^3*3^2*5^2
no of factors = (3+1)*(2+1)*(2+1)
=36 - 10 years agoHelpfull: Yes(1) No(1)
- total no of factors=36
- 10 years agoHelpfull: Yes(0) No(1)
