GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(255, 986) = 14790
GCD(255, 986) = ( 255 x 986 ) / 14790
= 255 / 986
= 255
Step2:
LCM(17, 379) = 6443
GCD(17, 379) = ( 17 x 379 ) / 6443
= 17 / 379
= 17
Step3:
LCM(1, 405) = 405
GCD(1, 405) = ( 1 x 405 ) / 405
= 1 / 405
= 1
So, Greatest Common Divisor of 255, 986, 379, 405 is 1
