LCD of 56, 69, 85 Calculator

Arrange the Inputs 56,69,85 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 328440

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(56, 69) = 1

LCD(56, 69) = ( 56 x 69 ) / 1

LCD(56, 69) = 3864 / 1

LCD(56, 69) = 3864

Step2:

Here we consider the LCD from the above i.e. 3864 as first number and the next as 85

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

GCF(3864, 85) = 1

LCD(3864, 85) = ( 3864 x 85 ) / 1

LCD(3864, 85) = 328440 / 1

LCD(3864, 85) = 328440

LCD of 56,69,85 is 328440
