Given numbers are 828, 789, 396, 571
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(828, 789) = 217764
GCD(828, 789) = ( 828 x 789 ) / 217764
= 828 / 789
= 828
Step2:
LCM(3, 396) = 396
GCD(3, 396) = ( 3 x 396 ) / 396
= 3 / 396
= 3
Step3:
LCM(3, 571) = 1713
GCD(3, 571) = ( 3 x 571 ) / 1713
= 3 / 571
= 3
So, Greatest Common Divisor of 828, 789, 396, 571 is 1
