GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(255, 385) = 19635
GCD(255, 385) = ( 255 x 385 ) / 19635
= 255 / 385
= 255
Step2:
LCM(5, 855) = 855
GCD(5, 855) = ( 5 x 855 ) / 855
= 5 / 855
= 5
Step3:
LCM(5, 521) = 2605
GCD(5, 521) = ( 5 x 521 ) / 2605
= 5 / 521
= 5
So, Greatest Common Divisor of 255, 385, 855, 521 is 1
