Given numbers are 656, 280, 189, 569

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

Apply this formula for all numbers.

Step1:

LCM(656, 280) = 22960

GCD(656, 280) = ( 656 x 280 ) / 22960

= 656 / 280

= 656

Step2:

LCM(8, 189) = 1512

GCD(8, 189) = ( 8 x 189 ) / 1512

= 8 / 189

= 8

Step3:

LCM(1, 569) = 569

GCD(1, 569) = ( 1 x 569 ) / 569

= 1 / 569

= 1

So, Greatest Common Divisor of 656, 280, 189, 569 is 1
