LCD of 40, 31, 87 Calculator

Arrange the Inputs 40,31,87 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 107880

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(40, 31) = 1

LCD(40, 31) = ( 40 x 31 ) / 1

LCD(40, 31) = 1240 / 1

LCD(40, 31) = 1240

Step2:

Here we consider the LCD from the above i.e. 1240 as first number and the next as 87

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

GCF(1240, 87) = 1

LCD(1240, 87) = ( 1240 x 87 ) / 1

LCD(1240, 87) = 107880 / 1

LCD(1240, 87) = 107880

LCD of 40,31,87 is 107880
