Given numbers are 195, 285, 481, 978

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

Apply this formula for all numbers.

Step1:

LCM(195, 285) = 3705

GCD(195, 285) = ( 195 x 285 ) / 3705

= 195 / 285

= 195

Step2:

LCM(15, 481) = 7215

GCD(15, 481) = ( 15 x 481 ) / 7215

= 15 / 481

= 15

Step3:

LCM(1, 978) = 978

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

= 1 / 978

= 1

So, Greatest Common Divisor of 195, 285, 481, 978 is 1
