Given numbers are 261, 645, 387, 237

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

Apply this formula for all numbers.

Step1:

LCM(261, 645) = 56115

GCD(261, 645) = ( 261 x 645 ) / 56115

= 261 / 645

= 261

Step2:

LCM(3, 387) = 387

GCD(3, 387) = ( 3 x 387 ) / 387

= 3 / 387

= 3

Step3:

LCM(3, 237) = 237

GCD(3, 237) = ( 3 x 237 ) / 237

= 3 / 237

= 3

So, Greatest Common Divisor of 261, 645, 387, 237 is 3
