Given numbers are 855, 109, 978

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

Apply this formula for all numbers.

Step1:

LCM(855, 109) = 93195

GCD(855, 109) = ( 855 x 109 ) / 93195

= 855 / 109

= 855

Step2:

LCM(1, 978) = 978

GCD(1, 978) = ( 1 x 978 ) / 978

= 1 / 978

= 1

So, Greatest Common Divisor of 855, 109, 978 is 1
