GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(549, 291) = 53253
GCD(549, 291) = ( 549 x 291 ) / 53253
= 549 / 291
= 549
Step2:
LCM(3, 216) = 216
GCD(3, 216) = ( 3 x 216 ) / 216
= 3 / 216
= 3
Step3:
LCM(3, 621) = 621
GCD(3, 621) = ( 3 x 621 ) / 621
= 3 / 621
= 3
So, Greatest Common Divisor of 549, 291, 216, 621 is 3
