Given numbers are 865, 447, 868, 825
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(865, 447) = 386655
GCD(865, 447) = ( 865 x 447 ) / 386655
= 865 / 447
= 865
Step2:
LCM(1, 868) = 868
GCD(1, 868) = ( 1 x 868 ) / 868
= 1 / 868
= 1
Step3:
LCM(1, 825) = 825
GCD(1, 825) = ( 1 x 825 ) / 825
= 1 / 825
= 1
So, Greatest Common Divisor of 865, 447, 868, 825 is 1
