Given numbers are 921, 231, 698, 930
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(921, 231) = 70917
GCD(921, 231) = ( 921 x 231 ) / 70917
= 921 / 231
= 921
Step2:
LCM(3, 698) = 2094
GCD(3, 698) = ( 3 x 698 ) / 2094
= 3 / 698
= 3
Step3:
LCM(1, 930) = 930
GCD(1, 930) = ( 1 x 930 ) / 930
= 1 / 930
= 1
So, Greatest Common Divisor of 921, 231, 698, 930 is 1
