Given numbers are 405, 140, 511
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(405, 140) = 11340
GCD(405, 140) = ( 405 x 140 ) / 11340
= 405 / 140
= 405
Step2:
LCM(5, 511) = 2555
GCD(5, 511) = ( 5 x 511 ) / 2555
= 5 / 511
= 5
So, Greatest Common Divisor of 405, 140, 511 is 1
