Make use of LCD Calculator to determine the Least Common Denominator of 142, 389, 139 i.e. 7678082 smallest integer divisible by all numbers.
LCD of 142, 389, 139 is 7678082
LCD(142, 389, 139) = 7678082
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
LCD of numbers 142, 389, 139 is 7678082
LCD(142, 389, 139) = 7678082
Arrange the Inputs 142,389,139 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 7678082
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(142, 389) = 1
LCD(142, 389) = ( 142 x 389 ) / 1
LCD(142, 389) = 55238 / 1
LCD(142, 389) = 55238
Step2:
Here we consider the LCD from the above i.e. 55238 as first number and the next as 139
The formula of LCD is LCD(a,b) = ( a x b) / GCF(a,b)
GCF(55238, 139) = 1
LCD(55238, 139) = ( 55238 x 139 ) / 1
LCD(55238, 139) = 7678082 / 1
LCD(55238, 139) = 7678082
LCD of 142,389,139 is 7678082
