Given numbers are 198, 771, 386, 921
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(198, 771) = 50886
GCD(198, 771) = ( 198 x 771 ) / 50886
= 198 / 771
= 198
Step2:
LCM(3, 386) = 1158
GCD(3, 386) = ( 3 x 386 ) / 1158
= 3 / 386
= 3
Step3:
LCM(1, 921) = 921
GCD(1, 921) = ( 1 x 921 ) / 921
= 1 / 921
= 1
So, Greatest Common Divisor of 198, 771, 386, 921 is 1
