LCD of 74, 21, 47 Calculator

Arrange the Inputs 74,21,47 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 73038

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(74, 21) = 1

LCD(74, 21) = ( 74 x 21 ) / 1

LCD(74, 21) = 1554 / 1

LCD(74, 21) = 1554

Step2:

Here we consider the LCD from the above i.e. 1554 as first number and the next as 47

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

GCF(1554, 47) = 1

LCD(1554, 47) = ( 1554 x 47 ) / 1

LCD(1554, 47) = 73038 / 1

LCD(1554, 47) = 73038

LCD of 74,21,47 is 73038
