A torpedo is about 19 ft long (mk-48)
Prime factorization of 20 in exponential form is: 22x5
They are: 10*11 = 110
8=23 12=22x3 20=22x5 28=22x7 18=2x32 27=33
4=22 10=2x5 So the LCM of 4 and 10 is 22x5=20 and the next multiples of both 4 and 10 are multiples of 20
You can multiply 2 times 11 times 5 to make 110! (2x11=22x5=110)
The integer that is a perfect square, perfect cube, and perfect fifth power is 64. This is because 64 is equal to 8^2, 4^3, and 2^6, making it a perfect square, cube, and fifth power. It is the only integer between 2 and 200000000000000 that satisfies all three conditions.
