LCD of 128, 421, 522 Calculator

Arrange the Inputs 128,421,522 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. 2 x 64 x 421 x 261 = 14064768

Therefore, LCD of 128,421,522 is 14064768

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(128, 421) = 1

LCD(128, 421) = ( 128 x 421 ) / 1

LCD(128, 421) = 53888 / 1

LCD(128, 421) = 53888

Step2:

Here we consider the LCD from the above i.e. 53888 as first number and the next as 522

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

GCF(53888, 522) = 2

LCD(53888, 522) = ( 53888 x 522 ) / 2

LCD(53888, 522) = 28129536 / 2

LCD(53888, 522) = 14064768

LCD of 128,421,522 is 14064768
