Given numbers are 658, 940, 530, 843
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(658, 940) = 6580
GCD(658, 940) = ( 658 x 940 ) / 6580
= 658 / 940
= 658
Step2:
LCM(94, 530) = 24910
GCD(94, 530) = ( 94 x 530 ) / 24910
= 94 / 530
= 94
Step3:
LCM(2, 843) = 1686
GCD(2, 843) = ( 2 x 843 ) / 1686
= 2 / 843
= 2
So, Greatest Common Divisor of 658, 940, 530, 843 is 1
