Given numbers are 865, 309, 665, 874
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(865, 309) = 267285
GCD(865, 309) = ( 865 x 309 ) / 267285
= 865 / 309
= 865
Step2:
LCM(1, 665) = 665
GCD(1, 665) = ( 1 x 665 ) / 665
= 1 / 665
= 1
Step3:
LCM(1, 874) = 874
GCD(1, 874) = ( 1 x 874 ) / 874
= 1 / 874
= 1
So, Greatest Common Divisor of 865, 309, 665, 874 is 1
