LCD of 689, 308, 215 Calculator

Arrange the Inputs 689,308,215 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 45625580

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(689, 308) = 1

LCD(689, 308) = ( 689 x 308 ) / 1

LCD(689, 308) = 212212 / 1

LCD(689, 308) = 212212

Step2:

Here we consider the LCD from the above i.e. 212212 as first number and the next as 215

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

GCF(212212, 215) = 1

LCD(212212, 215) = ( 212212 x 215 ) / 1

LCD(212212, 215) = 45625580 / 1

LCD(212212, 215) = 45625580

LCD of 689,308,215 is 45625580
