Make use of LCD Calculator to determine the Least Common Denominator of 387, 121, 454 i.e. 21259458 smallest integer divisible by all numbers.
LCD of 387, 121, 454 is 21259458
LCD(387, 121, 454) = 21259458
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
LCD of numbers 387, 121, 454 is 21259458
LCD(387, 121, 454) = 21259458
Arrange the Inputs 387,121,454 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 21259458
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(387, 121) = 1
LCD(387, 121) = ( 387 x 121 ) / 1
LCD(387, 121) = 46827 / 1
LCD(387, 121) = 46827
Step2:
Here we consider the LCD from the above i.e. 46827 as first number and the next as 454
The formula of LCD is LCD(a,b) = ( a x b) / GCF(a,b)
GCF(46827, 454) = 1
LCD(46827, 454) = ( 46827 x 454 ) / 1
LCD(46827, 454) = 21259458 / 1
LCD(46827, 454) = 21259458
LCD of 387,121,454 is 21259458
