Given numbers are 268, 661, 261, 247

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

Apply this formula for all numbers.

Step1:

LCM(268, 661) = 177148

GCD(268, 661) = ( 268 x 661 ) / 177148

= 268 / 661

= 268

Step2:

LCM(1, 261) = 261

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

= 1 / 261

= 1

Step3:

LCM(1, 247) = 247

GCD(1, 247) = ( 1 x 247 ) / 247

= 1 / 247

= 1

So, Greatest Common Divisor of 268, 661, 261, 247 is 1
