LCD of 89, 87, 40 Calculator

Arrange the Inputs 89,87,40 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 309720

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(89, 87) = 1

LCD(89, 87) = ( 89 x 87 ) / 1

LCD(89, 87) = 7743 / 1

LCD(89, 87) = 7743

Step2:

Here we consider the LCD from the above i.e. 7743 as first number and the next as 40

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

GCF(7743, 40) = 1

LCD(7743, 40) = ( 7743 x 40 ) / 1

LCD(7743, 40) = 309720 / 1

LCD(7743, 40) = 309720

LCD of 89,87,40 is 309720
