GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(891, 113) = 100683
GCD(891, 113) = ( 891 x 113 ) / 100683
= 891 / 113
= 891
Step2:
LCM(1, 328) = 328
GCD(1, 328) = ( 1 x 328 ) / 328
= 1 / 328
= 1
Step3:
LCM(1, 561) = 561
GCD(1, 561) = ( 1 x 561 ) / 561
= 1 / 561
= 1
So, Greatest Common Divisor of 891, 113, 328, 561 is 1
