Given numbers are 863, 861, 662, 178

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

Apply this formula for all numbers.

Step1:

LCM(863, 861) = 743043

GCD(863, 861) = ( 863 x 861 ) / 743043

= 863 / 861

= 863

Step2:

LCM(1, 662) = 662

GCD(1, 662) = ( 1 x 662 ) / 662

= 1 / 662

= 1

Step3:

LCM(1, 178) = 178

GCD(1, 178) = ( 1 x 178 ) / 178

= 1 / 178

= 1

So, Greatest Common Divisor of 863, 861, 662, 178 is 1
