Given numbers are 261, 570, 85, 215

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

Apply this formula for all numbers.

Step1:

LCM(261, 570) = 49590

GCD(261, 570) = ( 261 x 570 ) / 49590

= 261 / 570

= 261

Step2:

LCM(3, 85) = 255

GCD(3, 85) = ( 3 x 85 ) / 255

= 3 / 85

= 3

Step3:

LCM(1, 215) = 215

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

= 1 / 215

= 1

So, Greatest Common Divisor of 261, 570, 85, 215 is 1
