Given numbers are 604, 656, 561, 215

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

Apply this formula for all numbers.

Step1:

LCM(604, 656) = 99056

GCD(604, 656) = ( 604 x 656 ) / 99056

= 604 / 656

= 604

Step2:

LCM(4, 561) = 2244

GCD(4, 561) = ( 4 x 561 ) / 2244

= 4 / 561

= 4

Step3:

LCM(1, 215) = 215

GCD(1, 215) = ( 1 x 215 ) / 215

= 1 / 215

= 1

So, Greatest Common Divisor of 604, 656, 561, 215 is 1
