Given numbers are 521, 621, 168, 633
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(521, 621) = 323541
GCD(521, 621) = ( 521 x 621 ) / 323541
= 521 / 621
= 521
Step2:
LCM(1, 168) = 168
GCD(1, 168) = ( 1 x 168 ) / 168
= 1 / 168
= 1
Step3:
LCM(1, 633) = 633
GCD(1, 633) = ( 1 x 633 ) / 633
= 1 / 633
= 1
So, Greatest Common Divisor of 521, 621, 168, 633 is 1
