LCD of 281, 647, 390 Calculator

Arrange the Inputs 281,647,390 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 70904730

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(281, 647) = 1

LCD(281, 647) = ( 281 x 647 ) / 1

LCD(281, 647) = 181807 / 1

LCD(281, 647) = 181807

Step2:

Here we consider the LCD from the above i.e. 181807 as first number and the next as 390

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

GCF(181807, 390) = 1

LCD(181807, 390) = ( 181807 x 390 ) / 1

LCD(181807, 390) = 70904730 / 1

LCD(181807, 390) = 70904730

LCD of 281,647,390 is 70904730
