Given numbers are 455, 445, 389, 949
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(455, 445) = 40495
GCD(455, 445) = ( 455 x 445 ) / 40495
= 455 / 445
= 455
Step2:
LCM(5, 389) = 1945
GCD(5, 389) = ( 5 x 389 ) / 1945
= 5 / 389
= 5
Step3:
LCM(1, 949) = 949
GCD(1, 949) = ( 1 x 949 ) / 949
= 1 / 949
= 1
So, Greatest Common Divisor of 455, 445, 389, 949 is 1
