Given numbers are 978, 386, 307, 130

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

Apply this formula for all numbers.

Step1:

LCM(978, 386) = 188754

GCD(978, 386) = ( 978 x 386 ) / 188754

= 978 / 386

= 978

Step2:

LCM(2, 307) = 614

GCD(2, 307) = ( 2 x 307 ) / 614

= 2 / 307

= 2

Step3:

LCM(1, 130) = 130

GCD(1, 130) = ( 1 x 130 ) / 130

= 1 / 130

= 1

So, Greatest Common Divisor of 978, 386, 307, 130 is 1
