Given numbers are 725, 991, 198, 388

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

Apply this formula for all numbers.

Step1:

LCM(725, 991) = 718475

GCD(725, 991) = ( 725 x 991 ) / 718475

= 725 / 991

= 725

Step2:

LCM(1, 198) = 198

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

= 1 / 198

= 1

Step3:

LCM(1, 388) = 388

GCD(1, 388) = ( 1 x 388 ) / 388

= 1 / 388

= 1

So, Greatest Common Divisor of 725, 991, 198, 388 is 1
