Given numbers are 842, 774, 222, 781

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

Apply this formula for all numbers.

Step1:

LCM(842, 774) = 325854

GCD(842, 774) = ( 842 x 774 ) / 325854

= 842 / 774

= 842

Step2:

LCM(2, 222) = 222

GCD(2, 222) = ( 2 x 222 ) / 222

= 2 / 222

= 2

Step3:

LCM(2, 781) = 1562

GCD(2, 781) = ( 2 x 781 ) / 1562

= 2 / 781

= 2

So, Greatest Common Divisor of 842, 774, 222, 781 is 1
