Given numbers are 863, 136, 943, 643

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

Apply this formula for all numbers.

Step1:

LCM(863, 136) = 117368

GCD(863, 136) = ( 863 x 136 ) / 117368

= 863 / 136

= 863

Step2:

LCM(1, 943) = 943

GCD(1, 943) = ( 1 x 943 ) / 943

= 1 / 943

= 1

Step3:

LCM(1, 643) = 643

GCD(1, 643) = ( 1 x 643 ) / 643

= 1 / 643

= 1

So, Greatest Common Divisor of 863, 136, 943, 643 is 1
