Given numbers are 385, 991, 187, 653

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

Apply this formula for all numbers.

Step1:

LCM(385, 991) = 381535

GCD(385, 991) = ( 385 x 991 ) / 381535

= 385 / 991

= 385

Step2:

LCM(1, 187) = 187

GCD(1, 187) = ( 1 x 187 ) / 187

= 1 / 187

= 1

Step3:

LCM(1, 653) = 653

GCD(1, 653) = ( 1 x 653 ) / 653

= 1 / 653

= 1

So, Greatest Common Divisor of 385, 991, 187, 653 is 1
