Given numbers are 723, 342, 18, 658

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(723, 342) = 82422

GCD(723, 342) = ( 723 x 342 ) / 82422

= 723 / 342

= 723

Step2:

LCM(3, 18) = 18

GCD(3, 18) = ( 3 x 18 ) / 18

= 3 / 18

= 3

Step3:

LCM(3, 658) = 1974

GCD(3, 658) = ( 3 x 658 ) / 1974

= 3 / 658

= 3

So, Greatest Common Divisor of 723, 342, 18, 658 is 1
