To find the least common denominator (LCD) using prime factorization, start by breaking down each denominator into its prime factors. Then, identify the unique prime factors across all denominators, taking the highest power of each prime factor. Multiply these together to get the LCD. This method ensures that the LCD is the smallest number that can be evenly divided by all the original denominators.

What is lcd of 98 36 42?
To find the least common denominator (LCD) of the numbers 98, 36, and 42, we first determine their prime factorizations: 98 = 2 × 7^2 36 = 2^2 × 3^2 42 = 2 × 3 × 7 The LCD is obtained by taking the highest power of each prime number present in the factorizations. This gives us: LCD = 2^2 × 3^2 × 7^2 = 4 × 9 × 49 = 1764. Thus, the LCD of 98, 36, and 42 is 1764.

Find the LCD by dividing by prime numbers for 24 and 30?
24: 2 * 2 * 2 * 3 30: 2 * 3 * 5 LCD is 2^3 * 3 * 5 = 120
What is the LCD of two three five seven and eleven?
Because these are all prime numbers, the LCD will be 1. It'll also be the GCF.
What is the LCD of 11 and 24?
The two numbers are relatively prime, since 11 is a prime number and it doesn't evenly divide 24, so the LCM (the LCD of two fractions is the LCM of their denominators) is just their product: 264.
How can an understanding prime numbers help find the least common denominator?
Finding the prime factorisation of both denominators makes it easier to find the LCD. Simply make two columns, one for each denominator, and write the prime factors side by side. For each factor, note the larger exponent; then multiply out the list.
What is lcd of 98 36 42?
To find the least common denominator (LCD) of the numbers 98, 36, and 42, we first determine their prime factorizations: 98 = 2 × 7^2 36 = 2^2 × 3^2 42 = 2 × 3 × 7 The LCD is obtained by taking the highest power of each prime number present in the factorizations. This gives us: LCD = 2^2 × 3^2 × 7^2 = 4 × 9 × 49 = 1764. Thus, the LCD of 98, 36, and 42 is 1764.
