Given numbers are 668, 665, 198, 727

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

Apply this formula for all numbers.

Step1:

LCM(668, 665) = 444220

GCD(668, 665) = ( 668 x 665 ) / 444220

= 668 / 665

= 668

Step2:

LCM(1, 198) = 198

GCD(1, 198) = ( 1 x 198 ) / 198

= 1 / 198

= 1

Step3:

LCM(1, 727) = 727

GCD(1, 727) = ( 1 x 727 ) / 727

= 1 / 727

= 1

So, Greatest Common Divisor of 668, 665, 198, 727 is 1
