Given numbers are 871, 139, 620

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

Apply this formula for all numbers.

Step1:

LCM(871, 139) = 121069

GCD(871, 139) = ( 871 x 139 ) / 121069

= 871 / 139

= 871

Step2:

LCM(1, 620) = 620

GCD(1, 620) = ( 1 x 620 ) / 620

= 1 / 620

= 1

So, Greatest Common Divisor of 871, 139, 620 is 1
