Given numbers are 211, 861, 505, 265

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

Apply this formula for all numbers.

Step1:

LCM(211, 861) = 181671

GCD(211, 861) = ( 211 x 861 ) / 181671

= 211 / 861

= 211

Step2:

LCM(1, 505) = 505

GCD(1, 505) = ( 1 x 505 ) / 505

= 1 / 505

= 1

Step3:

LCM(1, 265) = 265

GCD(1, 265) = ( 1 x 265 ) / 265

= 1 / 265

= 1

So, Greatest Common Divisor of 211, 861, 505, 265 is 1
