LCD of 142, 165, 647 Calculator

Arrange the Inputs 142,165,647 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 15159210

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(142, 165) = 1

LCD(142, 165) = ( 142 x 165 ) / 1

LCD(142, 165) = 23430 / 1

LCD(142, 165) = 23430

Step2:

Here we consider the LCD from the above i.e. 23430 as first number and the next as 647

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

GCF(23430, 647) = 1

LCD(23430, 647) = ( 23430 x 647 ) / 1

LCD(23430, 647) = 15159210 / 1

LCD(23430, 647) = 15159210

LCD of 142,165,647 is 15159210
