Given numbers are 871, 781, 163, 942

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

Apply this formula for all numbers.

Step1:

LCM(871, 781) = 680251

GCD(871, 781) = ( 871 x 781 ) / 680251

= 871 / 781

= 871

Step2:

LCM(1, 163) = 163

GCD(1, 163) = ( 1 x 163 ) / 163

= 1 / 163

= 1

Step3:

LCM(1, 942) = 942

GCD(1, 942) = ( 1 x 942 ) / 942

= 1 / 942

= 1

So, Greatest Common Divisor of 871, 781, 163, 942 is 1
