Given numbers are 261, 273, 658, 138

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

Apply this formula for all numbers.

Step1:

LCM(261, 273) = 23751

GCD(261, 273) = ( 261 x 273 ) / 23751

= 261 / 273

= 261

Step2:

LCM(3, 658) = 1974

GCD(3, 658) = ( 3 x 658 ) / 1974

= 3 / 658

= 3

Step3:

LCM(1, 138) = 138

GCD(1, 138) = ( 1 x 138 ) / 138

= 1 / 138

= 1

So, Greatest Common Divisor of 261, 273, 658, 138 is 1
