Given numbers are 656, 332, 243, 845

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(656, 332) = 54448

GCD(656, 332) = ( 656 x 332 ) / 54448

= 656 / 332

= 656

Step2:

LCM(4, 243) = 972

GCD(4, 243) = ( 4 x 243 ) / 972

= 4 / 243

= 4

Step3:

LCM(1, 845) = 845

GCD(1, 845) = ( 1 x 845 ) / 845

= 1 / 845

= 1

So, Greatest Common Divisor of 656, 332, 243, 845 is 1
