Given numbers are 771, 285, 842, 188

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

Apply this formula for all numbers.

Step1:

LCM(771, 285) = 73245

GCD(771, 285) = ( 771 x 285 ) / 73245

= 771 / 285

= 771

Step2:

LCM(3, 842) = 2526

GCD(3, 842) = ( 3 x 842 ) / 2526

= 3 / 842

= 3

Step3:

LCM(1, 188) = 188

GCD(1, 188) = ( 1 x 188 ) / 188

= 1 / 188

= 1

So, Greatest Common Divisor of 771, 285, 842, 188 is 1
