LCD of 287, 287, 646 Calculator

Arrange the Inputs 287,287,646 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.

As all the numbers left in the last row are co primes you need not do the common division process further.

To obtain the Least Common Denominator, multiply the prime numbers with which you have divided the given numbers and the co primes in the last row i.e. 7 x 41 x 1 x 1 x 646 = 185402

Therefore, LCD of 287,287,646 is 185402

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(287, 287) = 287

LCD(287, 287) = ( 287 x 287 ) / 287

LCD(287, 287) = 82369 / 287

LCD(287, 287) = 287

Step2:

Here we consider the LCD from the above i.e. 287 as first number and the next as 646

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

GCF(287, 646) = 1

LCD(287, 646) = ( 287 x 646 ) / 1

LCD(287, 646) = 185402 / 1

LCD(287, 646) = 185402

LCD of 287,287,646 is 185402
