LCD of 247, 643, 131 Calculator

Arrange the Inputs 247,643,131 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 20805551

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(247, 643) = 1

LCD(247, 643) = ( 247 x 643 ) / 1

LCD(247, 643) = 158821 / 1

LCD(247, 643) = 158821

Step2:

Here we consider the LCD from the above i.e. 158821 as first number and the next as 131

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

GCF(158821, 131) = 1

LCD(158821, 131) = ( 158821 x 131 ) / 1

LCD(158821, 131) = 20805551 / 1

LCD(158821, 131) = 20805551

LCD of 247,643,131 is 20805551
