Given numbers are 861, 273, 862, 171
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(861, 273) = 11193
GCD(861, 273) = ( 861 x 273 ) / 11193
= 861 / 273
= 861
Step2:
LCM(21, 862) = 18102
GCD(21, 862) = ( 21 x 862 ) / 18102
= 21 / 862
= 21
Step3:
LCM(1, 171) = 171
GCD(1, 171) = ( 1 x 171 ) / 171
= 1 / 171
= 1
So, Greatest Common Divisor of 861, 273, 862, 171 is 1
