GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(651, 621) = 134757
GCD(651, 621) = ( 651 x 621 ) / 134757
= 651 / 621
= 651
Step2:
LCM(3, 504) = 504
GCD(3, 504) = ( 3 x 504 ) / 504
= 3 / 504
= 3
Step3:
LCM(3, 561) = 561
GCD(3, 561) = ( 3 x 561 ) / 561
= 3 / 561
= 3
So, Greatest Common Divisor of 651, 621, 504, 561 is 3
