LCD of 209, 688, 257 Calculator

Arrange the Inputs 209,688,257 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 36954544

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(209, 688) = 1

LCD(209, 688) = ( 209 x 688 ) / 1

LCD(209, 688) = 143792 / 1

LCD(209, 688) = 143792

Step2:

Here we consider the LCD from the above i.e. 143792 as first number and the next as 257

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

GCF(143792, 257) = 1

LCD(143792, 257) = ( 143792 x 257 ) / 1

LCD(143792, 257) = 36954544 / 1

LCD(143792, 257) = 36954544

LCD of 209,688,257 is 36954544
