GMAT Prep Exam Questions & Answers 2023/2024

GMAT Prep Exam Questions & Answers 2023/2024 Integers - ANSWER-Numbers, such as -1, 0, 1, 2, and 3, that have no fractional part. Integers include the counting numbers (1, 2, 3, …), their negative counterparts (-1, -2, -3, …), and 0. Factors - ANSWER-Positive integers that divide evenly into an integer. Factors are equal to or smaller than the integer in question. 12 is a factor of 12, as are 1, 2, 3, 4, and 6. Prime #s - ANSWER-A positive integer with exactly two factors: 1 and itself. The number 1 does not qualify as prime because it has only one factor, not two. The number 2 is the smallest prime number; it is also the only even prime number. The numbers 2, 3, 5, 7, 11, 13 etc. are prime. Prime Factorization - ANSWER-A way to express any number as a product of prime numbers Factor Foundation Rule - ANSWER-If a is a factor of b, and b is a factor of c, then a is also a factor of c. For example, 2 is a factor of 10. 10 is a factor of 60. Therefore, 2 is also a factor of 60. LCM - ANSWER-Least Common MULTIPLE refers to the smallest multiple of two (or more) integers. Multiples will be equal to or larger than the starting integers. The LCM of 12 and 30 is 60 because 60 is the smallest number that both 12 and 30 go into. Factorial - ANSWER-The factorial symbol is an exclamation mark (!) and is defined as the product of all integers from 1 up to and including the given number. 5! = 5 * 4 * 3 * 2 * 1 = 120. Dividend - ANSWER-The numerator of a fraction, or the part of a division operation that comes before the division sign. In the operation 22 ÷ 4, 22 is the dividend. Divisor - ANSWER-The denominator of a fraction, or the part of a division operation that comes after the division sign. In the operation 22 / 4, 4 is the divisor.
