Given numbers are 685, 255, 266, 111
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(685, 255) = 34935
GCD(685, 255) = ( 685 x 255 ) / 34935
= 685 / 255
= 685
Step2:
LCM(5, 266) = 1330
GCD(5, 266) = ( 5 x 266 ) / 1330
= 5 / 266
= 5
Step3:
LCM(1, 111) = 111
GCD(1, 111) = ( 1 x 111 ) / 111
= 1 / 111
= 1
So, Greatest Common Divisor of 685, 255, 266, 111 is 1
