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

Apply this formula for all numbers.

Step1:

LCM(782, 391) = 782

GCD(782, 391) = ( 782 x 391 ) / 782

= 782 / 391

= 782

Step2:

LCM(391, 999) = 390609

GCD(391, 999) = ( 391 x 999 ) / 390609

= 391 / 999

= 391

Step3:

LCM(1, 427) = 427

GCD(1, 427) = ( 1 x 427 ) / 427

= 1 / 427

= 1

So, Greatest Common Divisor of 782, 391, 999, 427 is 1
