Given numbers are 405, 458, 156, 773
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(405, 458) = 185490
GCD(405, 458) = ( 405 x 458 ) / 185490
= 405 / 458
= 405
Step2:
LCM(1, 156) = 156
GCD(1, 156) = ( 1 x 156 ) / 156
= 1 / 156
= 1
Step3:
LCM(1, 773) = 773
GCD(1, 773) = ( 1 x 773 ) / 773
= 1 / 773
= 1
So, Greatest Common Divisor of 405, 458, 156, 773 is 1
