What is the LCD of 3 4 and 7?
They're all prime numbers; 1 is the lcd * * * * * Sorry about the ignorance that permeates WA. First, they are not all primes, since 4 = 2*2 Also, the above answer refers to the HCF, not the LCD. The correct answer is 84
What is the LCD of 7 8 9?
To find the lcd of any set of numbers, you must find the lowest number which all of the numbers in the set can divide evenly into. For example, to find the lcd of 7,8, and 9, you must first see if there are any numbers that can divide by 2 of the three numbers in the set. An example of such a number is 56. 56/7 = 8 56/8 = 7 Once you have a number like this, the final step is to multiply that number by the other number in the set that does not divide into it (in this case, 9) 56x9 = 504 So, the lcd of 7, 8, and 9 is 504.
LCD for the numbers 7 and 17?
LCD = 119 (7x17=119)
LCD of 11 and 17?
Since 11 and 17 are both prime, you multiply them together to get the LCD which comes out to be 187.
What is the LCD for 3 5 and 7?
There is only one lowest common factor for primes: 1 All three numbers are prime, so the LCM is going to be their product: 105 ■
How can prime numbers be used in your everyday life?
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
What is LCD of 315?
You need at least two numbers to find an LCD.
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.
