Make use of LCD Calculator to determine the Least Common Denominator of 85, 63, 4 i.e. 21420 smallest integer divisible by all numbers.
LCD of 85, 63, 4 is 21420
LCD(85, 63, 4) = 21420
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
LCD of numbers 85, 63, 4 is 21420
LCD(85, 63, 4) = 21420
Arrange the Inputs 85,63,4 in a horizontal line separated by commas and divide them with a prime number. Note the quotients in the next row and divide with quotients with prime numbers again. Continue the process until you have all co primes in the last.
Given numbers has no common factors except 1. So, there LCD is their product i.e 21420
Step1:
Let's calculate the LCD of first two numbers
The formula of LCD is LCD(a,b) = ( a x b) / GCF(a,b)
GCF(85, 63) = 1
LCD(85, 63) = ( 85 x 63 ) / 1
LCD(85, 63) = 5355 / 1
LCD(85, 63) = 5355
Step2:
Here we consider the LCD from the above i.e. 5355 as first number and the next as 4
The formula of LCD is LCD(a,b) = ( a x b) / GCF(a,b)
GCF(5355, 4) = 1
LCD(5355, 4) = ( 5355 x 4 ) / 1
LCD(5355, 4) = 21420 / 1
LCD(5355, 4) = 21420
LCD of 85,63,4 is 21420
Here are some samples of LCD of Numbers calculations.
1. What is the LCD of 85, 63, 4?
Answer: LCD of 85, 63, 4 is 21420.
2. How to find LCD of 85, 63, 4 on a calculator?
Answer: You can find LCD of 85, 63, 4 by simply giving the inputs in the input field and clicking on the Calculator button next to it to get the concerned Least Common Denominator.
3. How to Find the LCD of 85, 63, 4?
Least Common Denominator of 85, 63, 4.
Step 1: Divide all the numbers with common prime numbers having remainder zero.
Step 2: Then multiply all the prime factors with last row quotient of common division that is LCD(85, 63, 4) = 21420.
