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 ■
