LCD of 640, 455, 350 Calculator

Arrange the Inputs 640,455,350 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 5 x 7 x 64 x 13 x 5 = 291200

Therefore, LCD of 640,455,350 is 291200

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(640, 455) = 5

LCD(640, 455) = ( 640 x 455 ) / 5

LCD(640, 455) = 291200 / 5

LCD(640, 455) = 58240

Step2:

Here we consider the LCD from the above i.e. 58240 as first number and the next as 350

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

GCF(58240, 350) = 70

LCD(58240, 350) = ( 58240 x 350 ) / 70

LCD(58240, 350) = 20384000 / 70

LCD(58240, 350) = 291200

LCD of 640,455,350 is 291200
