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

Apply this formula for all numbers.

Step1:

LCM(978, 786) = 128118

GCD(978, 786) = ( 978 x 786 ) / 128118

= 978 / 786

= 978

Step2:

LCM(6, 258) = 258

GCD(6, 258) = ( 6 x 258 ) / 258

= 6 / 258

= 6

Step3:

LCM(6, 782) = 2346

GCD(6, 782) = ( 6 x 782 ) / 2346

= 6 / 782

= 6

So, Greatest Common Divisor of 978, 786, 258, 782 is 2
