LCD of 57, 155, 821 Calculator

Arrange the Inputs 57,155,821 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 7253535

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(57, 155) = 1

LCD(57, 155) = ( 57 x 155 ) / 1

LCD(57, 155) = 8835 / 1

LCD(57, 155) = 8835

Step2:

Here we consider the LCD from the above i.e. 8835 as first number and the next as 821

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

GCF(8835, 821) = 1

LCD(8835, 821) = ( 8835 x 821 ) / 1

LCD(8835, 821) = 7253535 / 1

LCD(8835, 821) = 7253535

LCD of 57,155,821 is 7253535
