Given numbers are 405, 690, 227, 545
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(405, 690) = 18630
GCD(405, 690) = ( 405 x 690 ) / 18630
= 405 / 690
= 405
Step2:
LCM(15, 227) = 3405
GCD(15, 227) = ( 15 x 227 ) / 3405
= 15 / 227
= 15
Step3:
LCM(1, 545) = 545
GCD(1, 545) = ( 1 x 545 ) / 545
= 1 / 545
= 1
So, Greatest Common Divisor of 405, 690, 227, 545 is 1
