The LCD for 8 and 10 is 40. To find it, list the multiples of both numbers. The first multiple that they have in common is the LCD.
You need at least two numbers to find an LCD. If that's 12 and 115, the LCD is 1380. If that's 121 and 15, the LCD is 1815.
Two or more numbers are needed to find their LCD
Prime numbers are used to find the LCM of numbers Prime numbers are used to find the HCF of numbers Prime numbers are used to simplify fractions Prime numbers are used to find the LCD of fractions
You need at least two numbers to find an LCD.
24: 2 * 2 * 2 * 3 30: 2 * 3 * 5 LCD is 2^3 * 3 * 5 = 120
Because these are all prime numbers, the LCD will be 1. It'll also be the GCF.
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.
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.
