LCD of 641, 313, 640 Calculator

Arrange the Inputs 641,313,640 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 128405120

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(641, 313) = 1

LCD(641, 313) = ( 641 x 313 ) / 1

LCD(641, 313) = 200633 / 1

LCD(641, 313) = 200633

Step2:

Here we consider the LCD from the above i.e. 200633 as first number and the next as 640

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

GCF(200633, 640) = 1

LCD(200633, 640) = ( 200633 x 640 ) / 1

LCD(200633, 640) = 128405120 / 1

LCD(200633, 640) = 128405120

LCD of 641,313,640 is 128405120
