Given numbers are 813, 638, 252, 580
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(813, 638) = 518694
GCD(813, 638) = ( 813 x 638 ) / 518694
= 813 / 638
= 813
Step2:
LCM(1, 252) = 252
GCD(1, 252) = ( 1 x 252 ) / 252
= 1 / 252
= 1
Step3:
LCM(1, 580) = 580
GCD(1, 580) = ( 1 x 580 ) / 580
= 1 / 580
= 1
So, Greatest Common Divisor of 813, 638, 252, 580 is 1
