Given numbers are 135, 215, 285, 181

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

Apply this formula for all numbers.

Step1:

LCM(135, 215) = 5805

GCD(135, 215) = ( 135 x 215 ) / 5805

= 135 / 215

= 135

Step2:

LCM(5, 285) = 285

GCD(5, 285) = ( 5 x 285 ) / 285

= 5 / 285

= 5

Step3:

LCM(5, 181) = 905

GCD(5, 181) = ( 5 x 181 ) / 905

= 5 / 181

= 5

So, Greatest Common Divisor of 135, 215, 285, 181 is 1
