Given numbers are 685, 386, 880, 940
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(685, 386) = 264410
GCD(685, 386) = ( 685 x 386 ) / 264410
= 685 / 386
= 685
Step2:
LCM(1, 880) = 880
GCD(1, 880) = ( 1 x 880 ) / 880
= 1 / 880
= 1
Step3:
LCM(1, 940) = 940
GCD(1, 940) = ( 1 x 940 ) / 940
= 1 / 940
= 1
So, Greatest Common Divisor of 685, 386, 880, 940 is 1
