LCD of 21, 307, 785 Calculator

Arrange the Inputs 21,307,785 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 5060895

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(21, 307) = 1

LCD(21, 307) = ( 21 x 307 ) / 1

LCD(21, 307) = 6447 / 1

LCD(21, 307) = 6447

Step2:

Here we consider the LCD from the above i.e. 6447 as first number and the next as 785

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

GCF(6447, 785) = 1

LCD(6447, 785) = ( 6447 x 785 ) / 1

LCD(6447, 785) = 5060895 / 1

LCD(6447, 785) = 5060895

LCD of 21,307,785 is 5060895
