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

Apply this formula for all numbers.

Step1:

LCM(978, 455) = 444990

GCD(978, 455) = ( 978 x 455 ) / 444990

= 978 / 455

= 978

Step2:

LCM(1, 867) = 867

GCD(1, 867) = ( 1 x 867 ) / 867

= 1 / 867

= 1

So, Greatest Common Divisor of 978, 455, 867 is 1
