36.
The least number that is the product of two different primes that are squared is 6. This is because 6 is the product of 2 (which is squared as 2^2) and 3 (which is squared as 3^2), both of which are prime numbers. Any smaller number would not be the product of two different primes that are squared.
25 is the smallest two didgit squared number
The smallest prime factors are 2,3,5,7 thus the smallest number would be the product of these will be 210
30
n = 5 245 * 5 = 1225 which is 35 squared
If by "least number" you mean "smallest positive integer", then the answer is the product of the three smallest primes: 2x3x5 = 30
Logically, the smallest number with 4 different prime factors would have to be the product of the smallest four prime numbers. So the smallest natural number with four different prime factors is 210 (2*3*5*7).
A squared number is the product of an integer times itself. So, 16 is a squared number. 4 * 4 = 16.
1155, 3x5x7x11=1155.
5*n2
2×3×5×7=210
Their product.
