To find a common denominator for 25, 27, and 45, we need to determine the least common multiple (LCM) of these numbers. The prime factorization of 25 is 5^2, 27 is 3^3, and 45 is 3^2 * 5. The LCM is the product of the highest power of each prime factor that appears in any of the numbers, which in this case is 3^3 * 5^2 = 225. Therefore, 225 is the common denominator for 25, 27, and 45.

There is none because the Least Common Denominator (or LCD) refers to the Least Common Multiple (LCM) of the denominators of two or more fractions or mixed numbers. Even if you converted your whole numbers (x) to their fraction equivalents (x/1), the LCD would always be 1.

The greatest or highest common factor is the highest number that divides exactly into two or more numbers. 20: 1, 2, 4, 5, 10, 20 45: 1, 3, 5, 9, 15, 45 The greatest common factor for 20 and 45 is 5.
To find the highest common factor (HCF) of 225 and 270, we first need to find the factors of each number. The factors of 225 are 1, 3, 5, 9, 15, 25, 45, 75, and 225. The factors of 270 are 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 90, 135, and 270. The highest common factor of 225 and 270 is 45, as it is the largest factor that both numbers share.
