Given numbers are 770, 642, 392, 839

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

Apply this formula for all numbers.

Step1:

LCM(770, 642) = 247170

GCD(770, 642) = ( 770 x 642 ) / 247170

= 770 / 642

= 770

Step2:

LCM(2, 392) = 392

GCD(2, 392) = ( 2 x 392 ) / 392

= 2 / 392

= 2

Step3:

LCM(2, 839) = 1678

GCD(2, 839) = ( 2 x 839 ) / 1678

= 2 / 839

= 2

So, Greatest Common Divisor of 770, 642, 392, 839 is 1
