Given numbers are 869, 861, 162

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

Apply this formula for all numbers.

Step1:

LCM(869, 861) = 748209

GCD(869, 861) = ( 869 x 861 ) / 748209

= 869 / 861

= 869

Step2:

LCM(1, 162) = 162

GCD(1, 162) = ( 1 x 162 ) / 162

= 1 / 162

= 1

So, Greatest Common Divisor of 869, 861, 162 is 1
