GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(717, 621) = 148419
GCD(717, 621) = ( 717 x 621 ) / 148419
= 717 / 621
= 717
Step2:
LCM(3, 219) = 219
GCD(3, 219) = ( 3 x 219 ) / 219
= 3 / 219
= 3
Step3:
LCM(3, 291) = 291
GCD(3, 291) = ( 3 x 291 ) / 291
= 3 / 291
= 3
So, Greatest Common Divisor of 717, 621, 219, 291 is 3
