GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(816, 129) = 35088
GCD(816, 129) = ( 816 x 129 ) / 35088
= 816 / 129
= 816
Step2:
LCM(3, 621) = 621
GCD(3, 621) = ( 3 x 621 ) / 621
= 3 / 621
= 3
Step3:
LCM(3, 531) = 531
GCD(3, 531) = ( 3 x 531 ) / 531
= 3 / 531
= 3
So, Greatest Common Divisor of 816, 129, 621, 531 is 3
