OK
The answer is no - it is not possible. Reason:
The four lowest prime numbers are 2,3,5,7.
2x3x5x7 = 210 and 210 is larger than 200. You cannot have a number, less than 210, that is divisible by 4 DIFFERENT prime numbers.
Hope that helps.

A number that is divisible by 4 different prime numbers. Well, let's take the 4 lowest prime numbers:
2, 3, 5, and 7
2*3*5*7 = 210
Since the product of the 4 smallest prime numbers is 210, it is not possible to have a number less than 200 that is divisible by 4 different prime numbers.
Hope this makes sense :) Best of luck!

No. The smallest integer divisible by 3 different
odd primes is 3*5*7= 105, and so the smallest
integer divisible by 4 different primes is 2*3*5*7 = 210.

No
the 4 lowest prime numbers are
2; 3; 5;7
their products = 2*3*5*7 = 210 > 200
This means that the lowest number that is divisible by 4 different prime numbers is = 210

look at the first real prime numbers,
2, 3, 5, and 7
when you multiply these together you get
2 x 3 = 6 x 5 = 30 x 7 = 210
so, your answer is no
But, it could be true only if you recognize the number 1 as a prime number
then it would be 1 x 2 =2 x 3 = 6 x 5 = 30
given this your deside, do you think the number 1 is prime.
