GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(423, 549) = 25803
GCD(423, 549) = ( 423 x 549 ) / 25803
= 423 / 549
= 423
Step2:
LCM(9, 959) = 8631
GCD(9, 959) = ( 9 x 959 ) / 8631
= 9 / 959
= 9
Step3:
LCM(1, 621) = 621
GCD(1, 621) = ( 1 x 621 ) / 621
= 1 / 621
= 1
So, Greatest Common Divisor of 423, 549, 959, 621 is 1
