Given numbers are 839, 636, 778, 209

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

Apply this formula for all numbers.

Step1:

LCM(839, 636) = 533604

GCD(839, 636) = ( 839 x 636 ) / 533604

= 839 / 636

= 839

Step2:

LCM(1, 778) = 778

GCD(1, 778) = ( 1 x 778 ) / 778

= 1 / 778

= 1

Step3:

LCM(1, 209) = 209

GCD(1, 209) = ( 1 x 209 ) / 209

= 1 / 209

= 1

So, Greatest Common Divisor of 839, 636, 778, 209 is 1
