LCD of 621, 658, 407 Calculator

Arrange the Inputs 621,658,407 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 166307526

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(621, 658) = 1

LCD(621, 658) = ( 621 x 658 ) / 1

LCD(621, 658) = 408618 / 1

LCD(621, 658) = 408618

Step2:

Here we consider the LCD from the above i.e. 408618 as first number and the next as 407

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

GCF(408618, 407) = 1

LCD(408618, 407) = ( 408618 x 407 ) / 1

LCD(408618, 407) = 166307526 / 1

LCD(408618, 407) = 166307526

LCD of 621,658,407 is 166307526
