Given numbers are 678, 391, 446, 865
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(678, 391) = 265098
GCD(678, 391) = ( 678 x 391 ) / 265098
= 678 / 391
= 678
Step2:
LCM(1, 446) = 446
GCD(1, 446) = ( 1 x 446 ) / 446
= 1 / 446
= 1
Step3:
LCM(1, 865) = 865
GCD(1, 865) = ( 1 x 865 ) / 865
= 1 / 865
= 1
So, Greatest Common Divisor of 678, 391, 446, 865 is 1
