GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(865, 293) = 253445
GCD(865, 293) = ( 865 x 293 ) / 253445
= 865 / 293
= 865
Step2:
LCM(1, 578) = 578
GCD(1, 578) = ( 1 x 578 ) / 578
= 1 / 578
= 1
Step3:
LCM(1, 858) = 858
GCD(1, 858) = ( 1 x 858 ) / 858
= 1 / 858
= 1
So, Greatest Common Divisor of 865, 293, 578, 858 is 1
