Given numbers are 305, 389, 645, 894
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(305, 389) = 118645
GCD(305, 389) = ( 305 x 389 ) / 118645
= 305 / 389
= 305
Step2:
LCM(1, 645) = 645
GCD(1, 645) = ( 1 x 645 ) / 645
= 1 / 645
= 1
Step3:
LCM(1, 894) = 894
GCD(1, 894) = ( 1 x 894 ) / 894
= 1 / 894
= 1
So, Greatest Common Divisor of 305, 389, 645, 894 is 1
