GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(657, 543) = 118917
GCD(657, 543) = ( 657 x 543 ) / 118917
= 657 / 543
= 657
Step2:
LCM(3, 891) = 891
GCD(3, 891) = ( 3 x 891 ) / 891
= 3 / 891
= 3
Step3:
LCM(3, 203) = 609
GCD(3, 203) = ( 3 x 203 ) / 609
= 3 / 203
= 3
So, Greatest Common Divisor of 657, 543, 891, 203 is 1
