LCD of 257, 217, 123 Calculator

Arrange the Inputs 257,217,123 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 6859587

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(257, 217) = 1

LCD(257, 217) = ( 257 x 217 ) / 1

LCD(257, 217) = 55769 / 1

LCD(257, 217) = 55769

Step2:

Here we consider the LCD from the above i.e. 55769 as first number and the next as 123

The formula of LCD is LCD(a,b) = ( a x b) / GCF(a,b)

GCF(55769, 123) = 1

LCD(55769, 123) = ( 55769 x 123 ) / 1

LCD(55769, 123) = 6859587 / 1

LCD(55769, 123) = 6859587

LCD of 257,217,123 is 6859587
