Given numbers are 726, 321, 685, 440
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(726, 321) = 77682
GCD(726, 321) = ( 726 x 321 ) / 77682
= 726 / 321
= 726
Step2:
LCM(3, 685) = 2055
GCD(3, 685) = ( 3 x 685 ) / 2055
= 3 / 685
= 3
Step3:
LCM(1, 440) = 440
GCD(1, 440) = ( 1 x 440 ) / 440
= 1 / 440
= 1
So, Greatest Common Divisor of 726, 321, 685, 440 is 1
