Given numbers are 778, 890, 859, 394

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

Apply this formula for all numbers.

Step1:

LCM(778, 890) = 346210

GCD(778, 890) = ( 778 x 890 ) / 346210

= 778 / 890

= 778

Step2:

LCM(2, 859) = 1718

GCD(2, 859) = ( 2 x 859 ) / 1718

= 2 / 859

= 2

Step3:

LCM(1, 394) = 394

GCD(1, 394) = ( 1 x 394 ) / 394

= 1 / 394

= 1

So, Greatest Common Divisor of 778, 890, 859, 394 is 1
