Given numbers are 810, 285, 968, 445
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(810, 285) = 15390
GCD(810, 285) = ( 810 x 285 ) / 15390
= 810 / 285
= 810
Step2:
LCM(15, 968) = 14520
GCD(15, 968) = ( 15 x 968 ) / 14520
= 15 / 968
= 15
Step3:
LCM(1, 445) = 445
GCD(1, 445) = ( 1 x 445 ) / 445
= 1 / 445
= 1
So, Greatest Common Divisor of 810, 285, 968, 445 is 1
