LCD of 691, 424, 289 Calculator

Arrange the Inputs 691,424,289 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 84672376

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(691, 424) = 1

LCD(691, 424) = ( 691 x 424 ) / 1

LCD(691, 424) = 292984 / 1

LCD(691, 424) = 292984

Step2:

Here we consider the LCD from the above i.e. 292984 as first number and the next as 289

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

GCF(292984, 289) = 1

LCD(292984, 289) = ( 292984 x 289 ) / 1

LCD(292984, 289) = 84672376 / 1

LCD(292984, 289) = 84672376

LCD of 691,424,289 is 84672376
