Given numbers are 235, 978, 861

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

Apply this formula for all numbers.

Step1:

LCM(235, 978) = 229830

GCD(235, 978) = ( 235 x 978 ) / 229830

= 235 / 978

= 235

Step2:

LCM(1, 861) = 861

GCD(1, 861) = ( 1 x 861 ) / 861

= 1 / 861

= 1

So, Greatest Common Divisor of 235, 978, 861 is 1
