Given numbers are 481, 891, 254, 689
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(481, 891) = 428571
GCD(481, 891) = ( 481 x 891 ) / 428571
= 481 / 891
= 481
Step2:
LCM(1, 254) = 254
GCD(1, 254) = ( 1 x 254 ) / 254
= 1 / 254
= 1
Step3:
LCM(1, 689) = 689
GCD(1, 689) = ( 1 x 689 ) / 689
= 1 / 689
= 1
So, Greatest Common Divisor of 481, 891, 254, 689 is 1
