Given numbers are 261, 478, 389, 177

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

Apply this formula for all numbers.

Step1:

LCM(261, 478) = 124758

GCD(261, 478) = ( 261 x 478 ) / 124758

= 261 / 478

= 261

Step2:

LCM(1, 389) = 389

GCD(1, 389) = ( 1 x 389 ) / 389

= 1 / 389

= 1

Step3:

LCM(1, 177) = 177

GCD(1, 177) = ( 1 x 177 ) / 177

= 1 / 177

= 1

So, Greatest Common Divisor of 261, 478, 389, 177 is 1
