LCD of 397, 403, 890 Calculator

Arrange the Inputs 397,403,890 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 142391990

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(397, 403) = 1

LCD(397, 403) = ( 397 x 403 ) / 1

LCD(397, 403) = 159991 / 1

LCD(397, 403) = 159991

Step2:

Here we consider the LCD from the above i.e. 159991 as first number and the next as 890

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

GCF(159991, 890) = 1

LCD(159991, 890) = ( 159991 x 890 ) / 1

LCD(159991, 890) = 142391990 / 1

LCD(159991, 890) = 142391990

LCD of 397,403,890 is 142391990
