Given numbers are 978, 255, 862

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

Apply this formula for all numbers.

Step1:

LCM(978, 255) = 83130

GCD(978, 255) = ( 978 x 255 ) / 83130

= 978 / 255

= 978

Step2:

LCM(3, 862) = 2586

GCD(3, 862) = ( 3 x 862 ) / 2586

= 3 / 862

= 3

So, Greatest Common Divisor of 978, 255, 862 is 1
