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

Apply this formula for all numbers.

Step1:

LCM(978, 538) = 263082

GCD(978, 538) = ( 978 x 538 ) / 263082

= 978 / 538

= 978

Step2:

LCM(2, 865) = 1730

GCD(2, 865) = ( 2 x 865 ) / 1730

= 2 / 865

= 2

So, Greatest Common Divisor of 978, 538, 865 is 1
