Given numbers are 261, 860, 535, 641

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

Apply this formula for all numbers.

Step1:

LCM(261, 860) = 224460

GCD(261, 860) = ( 261 x 860 ) / 224460

= 261 / 860

= 261

Step2:

LCM(1, 535) = 535

GCD(1, 535) = ( 1 x 535 ) / 535

= 1 / 535

= 1

Step3:

LCM(1, 641) = 641

GCD(1, 641) = ( 1 x 641 ) / 641

= 1 / 641

= 1

So, Greatest Common Divisor of 261, 860, 535, 641 is 1
