Given numbers are 261, 140, 961

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

Apply this formula for all numbers.

Step1:

LCM(261, 140) = 36540

GCD(261, 140) = ( 261 x 140 ) / 36540

= 261 / 140

= 261

Step2:

LCM(1, 961) = 961

GCD(1, 961) = ( 1 x 961 ) / 961

= 1 / 961

= 1

So, Greatest Common Divisor of 261, 140, 961 is 1
