Given numbers are 261, 666, 656, 573

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

Apply this formula for all numbers.

Step1:

LCM(261, 666) = 19314

GCD(261, 666) = ( 261 x 666 ) / 19314

= 261 / 666

= 261

Step2:

LCM(9, 656) = 5904

GCD(9, 656) = ( 9 x 656 ) / 5904

= 9 / 656

= 9

Step3:

LCM(1, 573) = 573

GCD(1, 573) = ( 1 x 573 ) / 573

= 1 / 573

= 1

So, Greatest Common Divisor of 261, 666, 656, 573 is 1
