The factors of 54 are 1, 54, 3, 18, 2, 27, 6 and 9. Factors are the numbers that evenly multiply into a given number.
Continue ReadingFactor pairs equal a given number, when multiplied together in factorization. Every number has at least one factor pair: 1 and itself. Numbers that can only be factored by 1 and themselves are prime numbers. Because 54 has more than one factorization, it is a composite number.
Multiplying 1 and 54 produces 54, as does 3 and 18, 2 and 27, and 6 and 9. Each of these is a factor pair of 54.
Prime factorization produces a number, using only the prime number factors. The prime numbers of 54 are 2 and 3, because each of these numbers has exactly one factor pair. Therefore, the prime factorization of 54 is 2 multiplied by 3 multiplied by 3 multiplied by 3.
Learn more about ArithmeticIn a multiplication table, the numbers in the first row and the first column are all factors, and the numbers in the interior rows and columns are all products. To use the table to find the answer to a multiplication problem, locate one factor in the first row and the other factor in the first column. The number in the interior square where the column and row meet is the product of the problem.
Full Answer >A factor rainbow is a way of writing factors for numbers using a series of arcs. It helps students ensure they have all the factors by listing them in consecutive order.
Full Answer >Multiplying two numbers with like signs, either two positive numbers or two negative numbers, yields a positive number. Numbers not preceded by a sign are considered positive. Those numbers preceded by a minus sign, sometimes surrounded by parenthesis, are negative numbers.
Full Answer >Long division on large numbers is performed by breaking down the number being divided, also known as the dividend, by place value. The digits of the dividend are treated as individual long division problems, with the remainder successively carrying over to the next digit being worked, until the smallest place value in the dividend is reached.
