Given numbers are 420, 633, 726, 345
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(420, 633) = 88620
GCD(420, 633) = ( 420 x 633 ) / 88620
= 420 / 633
= 420
Step2:
LCM(3, 726) = 726
GCD(3, 726) = ( 3 x 726 ) / 726
= 3 / 726
= 3
Step3:
LCM(3, 345) = 345
GCD(3, 345) = ( 3 x 345 ) / 345
= 3 / 345
= 3
So, Greatest Common Divisor of 420, 633, 726, 345 is 3
