LCD of 781, 211, 621 Calculator

Arrange the Inputs 781,211,621 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 102335211

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(781, 211) = 1

LCD(781, 211) = ( 781 x 211 ) / 1

LCD(781, 211) = 164791 / 1

LCD(781, 211) = 164791

Step2:

Here we consider the LCD from the above i.e. 164791 as first number and the next as 621

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

GCF(164791, 621) = 1

LCD(164791, 621) = ( 164791 x 621 ) / 1

LCD(164791, 621) = 102335211 / 1

LCD(164791, 621) = 102335211

LCD of 781,211,621 is 102335211
