Given numbers are 903, 207, 91, 981

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

Apply this formula for all numbers.

Step1:

LCM(903, 207) = 62307

GCD(903, 207) = ( 903 x 207 ) / 62307

= 903 / 207

= 903

Step2:

LCM(3, 91) = 273

GCD(3, 91) = ( 3 x 91 ) / 273

= 3 / 91

= 3

Step3:

LCM(1, 981) = 981

GCD(1, 981) = ( 1 x 981 ) / 981

= 1 / 981

= 1

So, Greatest Common Divisor of 903, 207, 91, 981 is 1
