Given numbers are 297, 456, 254, 891
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(297, 456) = 45144
GCD(297, 456) = ( 297 x 456 ) / 45144
= 297 / 456
= 297
Step2:
LCM(3, 254) = 762
GCD(3, 254) = ( 3 x 254 ) / 762
= 3 / 254
= 3
Step3:
LCM(1, 891) = 891
GCD(1, 891) = ( 1 x 891 ) / 891
= 1 / 891
= 1
So, Greatest Common Divisor of 297, 456, 254, 891 is 1
