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

Apply this formula for all numbers.

Step1:

LCM(411, 861) = 117957

GCD(411, 861) = ( 411 x 861 ) / 117957

= 411 / 861

= 411

Step2:

LCM(3, 135) = 135

GCD(3, 135) = ( 3 x 135 ) / 135

= 3 / 135

= 3

Step3:

LCM(3, 978) = 978

GCD(3, 978) = ( 3 x 978 ) / 978

= 3 / 978

= 3

So, Greatest Common Divisor of 411, 861, 135, 978 is 3
