Given numbers are 265, 639, 186, 261

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

Apply this formula for all numbers.

Step1:

LCM(265, 639) = 169335

GCD(265, 639) = ( 265 x 639 ) / 169335

= 265 / 639

= 265

Step2:

LCM(1, 186) = 186

GCD(1, 186) = ( 1 x 186 ) / 186

= 1 / 186

= 1

Step3:

LCM(1, 261) = 261

GCD(1, 261) = ( 1 x 261 ) / 261

= 1 / 261

= 1

So, Greatest Common Divisor of 265, 639, 186, 261 is 1
