Given numbers are 871, 820, 965

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

Apply this formula for all numbers.

Step1:

LCM(871, 820) = 714220

GCD(871, 820) = ( 871 x 820 ) / 714220

= 871 / 820

= 871

Step2:

LCM(1, 965) = 965

GCD(1, 965) = ( 1 x 965 ) / 965

= 1 / 965

= 1

So, Greatest Common Divisor of 871, 820, 965 is 1
