SHSAT Math2Natural Numbers/Counting Numbers - correct answer 1,2,3. . . (0 is not included) Whole Numbers - correct answer 0, 1, 2, 3. . . . (0 is included) Integers - correct answer Whole numbers and their opposites (. . . -3, -2, -1, 0, 1, 2, 3. . .) Prime Numbers - correct answer Integers greater than 1 and have exactly 2 factors (1 and themselves); 2 is only even prime number Composite Numbers - correct answer Integers with more than 2 factors Distinct Numbers - correct answer Numbers that are different from each other Even Numbers - correct answer Integers divisible by 2 (can be negative) Odd Numbers - correct answer integers not divisible by 2 (can be negative) GCF (Greatest Common Factor) - correct answer the largest common factor of two or more given numbers (24, 36, 60 = 12) LCM (Least Common Multiple) - correct answer The smallest whole number greater than 0 that is a common multiple of each of two or more numbers. (24, 36, 60 = 360) Divisible by 2 - correct answer The last digit is even (0,2,4,6,8) Divisible by 3 - correct answer The sum of the digits is divisible by 3 Divisible by 4 - correct answer The last 2 digits are divisible by 4 Divisible by 5 - correct answer The last digit is 0 or 5 Divisible by 6 - correct answer The number is divisible by both 2 and 3 Divisible by 9 - correct answer If the sum of the digits is divisible by 9 Divisible by 10 - correct answer The number ends in 0 Sum of two prime numbers is always even except when. . . - correct answer One of the numbers is 2 Three consecutive numbers contain at least one number that is divisible by ___ and at least one number that is divisible by ___ - correct answer 2, 3 Rational number - correct answer A number that can be written as a fraction or repeating decimal How do you figure out the GCF of two numbers? - correct answer Do prime factorization of each and multiply their common prime factors. So, if the prime factorization of one number is 2*2*3*7 and the other is 2*3, the GCF is 2*3 or 6. How do you figure out the LCM of two numbers? - correct answer Do prime factorization of each and then write out the prime factors of each number on top of one another. For each prime factor, see what the greatest number of that prime factor is for each and write that number down that many times. For example, to do the LCM of 42, 12; 42=7*2*3 and 12=2*2*3, so you multiply: 7*2*2*3. If both numbers have one of a prime factor, you enter that prime factor once. If only one of the numbers has a certain prime factor, you also only enter that number once. If one number has two of a given prime factor and the other number only has one of that prime factor, you enter that prime factor twice. Median - correct answer Middle number in ordered set if odd number of elements. If even number, average of two middle numbers in the set.
