LCD of 77, 780, 391 Calculator

Arrange the Inputs 77,780,391 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 23483460

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(77, 780) = 1

LCD(77, 780) = ( 77 x 780 ) / 1

LCD(77, 780) = 60060 / 1

LCD(77, 780) = 60060

Step2:

Here we consider the LCD from the above i.e. 60060 as first number and the next as 391

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

GCF(60060, 391) = 1

LCD(60060, 391) = ( 60060 x 391 ) / 1

LCD(60060, 391) = 23483460 / 1

LCD(60060, 391) = 23483460

LCD of 77,780,391 is 23483460
