Given numbers are 305, 716, 145, 823
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(305, 716) = 218380
GCD(305, 716) = ( 305 x 716 ) / 218380
= 305 / 716
= 305
Step2:
LCM(1, 145) = 145
GCD(1, 145) = ( 1 x 145 ) / 145
= 1 / 145
= 1
Step3:
LCM(1, 823) = 823
GCD(1, 823) = ( 1 x 823 ) / 823
= 1 / 823
= 1
So, Greatest Common Divisor of 305, 716, 145, 823 is 1
