GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(297, 141) = 13959
GCD(297, 141) = ( 297 x 141 ) / 13959
= 297 / 141
= 297
Step2:
LCM(3, 891) = 891
GCD(3, 891) = ( 3 x 891 ) / 891
= 3 / 891
= 3
Step3:
LCM(3, 486) = 486
GCD(3, 486) = ( 3 x 486 ) / 486
= 3 / 486
= 3
So, Greatest Common Divisor of 297, 141, 891, 486 is 3
