Given numbers are 391, 711, 246, 465
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(391, 711) = 278001
GCD(391, 711) = ( 391 x 711 ) / 278001
= 391 / 711
= 391
Step2:
LCM(1, 246) = 246
GCD(1, 246) = ( 1 x 246 ) / 246
= 1 / 246
= 1
Step3:
LCM(1, 465) = 465
GCD(1, 465) = ( 1 x 465 ) / 465
= 1 / 465
= 1
So, Greatest Common Divisor of 391, 711, 246, 465 is 1
