Study Guide with Complete Solutions
undefined - ️️ Correct-division by zero; a/bc is ___ if b or c is equal to zero
real number - ️️ Correct-number that has a location on the number line
imaginary number - ️️ Correct-on the ACT, ___ numbers involve the ...
multiples - ✔️✔️Correct-the ___ of integer n are the integers that n divides into with no
remainder. (twelve is a ___ of six)
prime number - ✔️✔️Correct-a positive integer that has exactly two positive integer
factors, one and the integer itself.
how to find the prime factorization of a number - ✔️✔️Correct-keep breaking the integer
up into factors until all factors are prime; 36 = 4 x 9 = 2 x 2 x 3 x 3
how to determine whether two integers are relative primes - ✔️✔️Correct-break both
down to their prime factorizations. if they have NO PRIME FACTORS IN COMMON,
they are relative primes
how to find a common multiple of two numbers - ✔️✔️Correct-multiply the two numbers
together (this will not be the least common multiple unless the two are relative primes)
how to find the LCM, or the least common multiple - ✔️✔️Correct-check out the multiples
of the larger number until you find one that's also a multiple of the smaller; to find the
LCM of 12 and 15, take the multiples of 15: 15 not divisible by 12, neither is 30 and
neither is 45. but the next multiple of 15, 60, is divisible by 12 so its the LCM
multiples of 2 and 4 - ✔️✔️Correct-an integer is divisible by 2 if the last digit is even and
divisible by 4 if the last two digits form a multiple of 4
