Given numbers are 423, 921, 750, 686
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(423, 921) = 129861
GCD(423, 921) = ( 423 x 921 ) / 129861
= 423 / 921
= 423
Step2:
LCM(3, 750) = 750
GCD(3, 750) = ( 3 x 750 ) / 750
= 3 / 750
= 3
Step3:
LCM(3, 686) = 2058
GCD(3, 686) = ( 3 x 686 ) / 2058
= 3 / 686
= 3
So, Greatest Common Divisor of 423, 921, 750, 686 is 1
