Given numbers are 813, 800, 512, 557
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(813, 800) = 650400
GCD(813, 800) = ( 813 x 800 ) / 650400
= 813 / 800
= 813
Step2:
LCM(1, 512) = 512
GCD(1, 512) = ( 1 x 512 ) / 512
= 1 / 512
= 1
Step3:
LCM(1, 557) = 557
GCD(1, 557) = ( 1 x 557 ) / 557
= 1 / 557
= 1
So, Greatest Common Divisor of 813, 800, 512, 557 is 1
